1. Aspirin, also known as acetylsalicylic acid (C9H8O4) is a medication, often used to relieve minor aches and pains and reduce fever. Each tablet contains 325 mg of aspirin, and a typical adult dose is two tablets every four hours. • Determine the molar mass of aspirin. Show all steps to find the answer.
• Calculate the number of moles of aspirin in a single tablet. Show all steps to find the answer.
• Calculate the number of moles of aspirin that an adult would have taken if she took four doses of aspirin in one day. Show all steps to find the answer.

Explain which group an element with the electron configuration 1s2 2s2 2p6 3s2 3p6 3d1 4s2 belongs to.

Consider three unlabeled bottles, each contain small pieces of one of the following metals. - magnesium - sodium - silver the following reagents are used for identifying the metals. - pure water - a solution of 1.0 molar hcl - a solution of concentrated hno3 (a) which metal can be easily identified because it is much softer than the other two? describe a chemical test that distinguishes this metal from the other two, using only one of the reagents above. write a balanced chemical equation for the reaction that occurs. (b) one of the other two metals reacts readily with the hcl solution. identify the metal and write the balanced chemical equation for the reaction that occurs when this metal is added to the hcl solution. use the table of standard reduction potentials (attached) to account for the fact that this metal reacts with hcl while the other does not. (c) the one remaining metal reacts with the concentrated hno3 solution. write a balanced chemical equation for the reaction that occurs. (d) the solution obtained in (c) is diluted and a few drops of 1 m hcl is added. describe what would be observed. write a balanced chemical equation for the reaction that occurs.
