How to Use a Volumetric Flask

How to Use a Volumetric Flask A volumetric flask is a piece of laboratory glassware that is used to prepare and measure chemical solutions. It is used to make up a solution to a known volume. Volumetric flasks measure volumes much more precisely than beakers and Erlenmeyer flasks. How to Recognize a Volumetric Flask A volumetric flask is characterized by a bulb and a long neck. Most volumetric flasks have flattened bottoms so that they can be placed on a lab bench or other surface, though some volumetric flasks have rounded bottoms and must be handled with special protective equipment. How to Use a Volumetric Flask To prepare a solution in a volumetric flask, follow these steps: Measure and add the solute for the solution.Add enough solvent to dissolve the solute.Continue to add solvent until you near the line marked on the volumetric flask.Use a pipette or dropper to fill the volumetric flask, using the meniscus of the solution and the line on the flask to determine your endpoint.Seal the volumetric flask and invert it to thoroughly mix the solution.

Book review - Essay Example Utilitarianism is a philosophical movement essentially defined by what pleases the most people. Morality is defined by the majority. The trend that follows is one of hedonistic pursuits with the avoidance of pain. Initially, this philosophy was delineated by Jeremy Bentham and later expounded on by John Stuart Mills. Utilitarian proponents view all things as measured by the amount of happiness they can elicit rather than the intrinsic value. The moral compass of any individual is gained from actual experiences, rather than any set of core values instilled in the individual by a higher power. Utilitarianism has largely been successful amongst the English, who consider all experiences derived from the five senses. This doctrine is contrary necessitates a physical experience as a means of understanding right from wrong, morality from immorality. The lineage of such a concept can be traced back to Hobbes’ code of ethics as measured by what best serves the individual while disregarding others. However, the utilitarian ideals are more carefully crafted, taking consideration of the greater good for the greater number of individuals. It is true that a perfect society in which all can be perfectly content is impossible. Therefore the only possible recourse is to try to please the majority. That is the fundamental premise of a democracy which holds to a standard of majority rule. As exemplified in various democracies around the world, a rule by the people has tremendous success while political regimes that are totalitarian in nature are not as successful socioeconomically. In Albert Camus’s The Stranger, Mersault is indifferent to his morally reprehensible acts. He represents the universe in his detachment to the events in his life. Even Camus’s style of of using first person to convey the story of his protagonist Mersault gives the impression of his conscience and the adopted morality that guides his thoughts

Business Legal Structures - Essay Example The owner of the business is usually the person who runs the day-to-day activities and responsibilities of the business (Kuratko & Hodgetts 190). Accordingly, that one individual also owns all properties and assets of the business, and all the profits realized from the business operations. As such, these individuals are also responsible for all the debts or liabilities, as the law and the public views that individual as the same entity with the business (Miller & Jentz 530). Although it is looked upon as a business easy to run with several advantages, it has a number of disadvantages as well. The merits of sole proprietorship are that it is the least expensive type of business in both formation and organization, and the proprietor has total control over the business, thus allows business decision making according to their appropriation by the business law parameters (Miller & Hollowell 385). In addition, the owners receive all the profits from the business, no additional taxation, no business reporting to government agencies, and easy dissolution if so desired. Further, the owner of the business only has to secure the few legal requirements like tax identification number, necessary licenses, and certificates to start business operations. It is only this form of business operation where decision making is fast. This is because the owner does not need to make consultations as it is the case with other forms of business managements. The most significant demerit of sole proprietorship is that the proprietor has unlimited liability, and thus legally responsibility for all liabilities or debts of the business. Other disadvantages include the difficulty of selling or transferring part or all of the business resulting from the tax consequences associated with converting this from of business to a corporation or company (Miller & Jentz 532). In addition, the proprietor lacks financial support as enjoyed by other forms of legal structures, and the business risks failure on the incapacitation of the proprietor as all management responsibilities lies upon them. Again, the business has difficulties in attracting high-caliber employees, as well as deducting some employee benefits like medical insurance. If it happens that the business in its operation incurs a loss, the proprietor suffers it alone, with no one to share the liability with. Partnership The second form of business is partnership. A partnership is a form of business where ownership lays between two or more people. Similar to sole proprietorship, the laws does not recognize business partnerships as different entities from their owners (Laro & Pratt 88). There are, however, limited liabilities partnerships where the liability of the partner is limited to their share of investment in the business, though there must be at least one partner who remains liable (unlimited) for the debts of the business (Kuratko & Hodgetts 192). Nonetheless, the partners is required to have a legal agreement that stipulates how decisions concerning the business will be made, profit sharing, resolutions of disputes, admission of future
