Question

7.13 g of NaF are dissolved in enough water to make 201 mL of solution. What is the molarity of this solution

Answer 1

0.846M

Step-by-step explanation:

To find the molarity, we have an equation: moles ÷ liter.

To find the moles of NaF, take the gram ÷ molar mass of NaF

7.13/42.0 = 0.170 moles of NaF

201 ml ÷ 1000 = 0.201L

0.170 ÷ 0.201 = 0.846M
