Introduction to Stoichiometry - Chemical Formulas

Label the work for each question below. Circle your final answer. DO NOT answer each question next to the question. The assignment is worth 20 points.

1) Use , find each question below:

a) How many moles of Ga are in 2.361 mole ?

b) What is the molar mass of

c) If chemical reaction produces 26.83 g , how many moles were produced? 

d) If a procedure requires 0.500 mol , how many grams should be massed on the balance?

what relevance does the song "We didn't start the fire" by billy Joel relate to stereochemistry in organic chemistry? Can you give an example using a molecule?

What would be the isomers of this diels alder reaction?? with stereochemistry?? Can you show the structure of the products? one side is C=S and the other side is C=O. I want to know stereochemistry of all possible products.

When I'm doing Van Der Waals equation for non ideal gas in chemistry, can you pls explain how to, algebraically manipulate the variables, solve for v (isolate v on on 1 side) and how to solve for n?
