Calculate the molarity of a solution made by dissolving 0.0715 mol Na2SO4 in enough water to form 550 mL of solution.

While we're at it...

How many milliliters of 10.6 M HCl solution are needed to obtain 0.205 mol of HCl?

Also...

How many grams of solute are present in 50.0 mL of 1.33 M CoSO4?

In conclusion...

If 4.50 g of (NH4)2SO4 is dissolved in enough water to form 250. mL of solution, what is the molarity of the solution?

For #1, the definition is
M = mols/L of solution. Substitute and you have it.
