4 Questions on molarity that I really don't understand. I have the formulas, but they don't seem to fit in to the question right. Please take a look, thanks!

1. Calculate the weight, in grams, of HNO3 present in 1.0 litre of 0.10M of solution.

2. What is the concentration, in moles per litre of 60.0g of NaOH in 500.0ml solution?

3. What volume of solution is required in each of the following if 4.0 moles of CuSO4 are used to make a 1.0M solution?

4. How can a solution be prepared to make 5.00L of a 6.00M solution of potassium hydroxide from a 8.00M stock solution?

1. You have 0.1 mol of HNO3 because you have one liter
H = 1
N = 14
O3 = 3*16 = 48
so
63 grams/mol
so
6.3 grams

The others are very similar.

what is the difference between moles(mol) and molarity(M)?
