Question

What is the molarity of 1. 5 liters of an aqueous solution that contains 52 grams of lithium fluoride.

Answer 1

1.3 M

Step-by-step explanation:

The formula mass of lithium fluoride is 7+19=26 g/mol. This means that in 52 grams of LiF, there is 2 moles.

Molarity = (moles of solute)/(liters of solution), so the answer is 2/1.5 = 1.3 M
