Question

Lithium nitrate has a molecular mass of 68.95 g/mol. What is the molarity of the solution that results from dissolving 20.6 g of lithium nitrate in 1.1 L of water?

Question 4

Potassium sulfate has a molecular mass of 174.3 g/mol. How many grams of potassium sulfate do you need to dissolve in 0.439 liters of water to prepare a solution with 0.708 molarity?

Answer 1

3: the molarity of the lithium nitrate solution is 0.272 M.

4: we need to dissolve 54.063 g of potassium sulfate in 0.439 L of water to prepare a 0.708 M solution.
