Question

a solution is made by adding 27.5 g of calcium fluoride to enough water to make 1.00L. what is the concentration (molarity)?

Answer 1

Answer:

The concentration will be 0.352 M

Data Given

mass of calcium fluoride = 27.5 g

molar mass of calcium fluoride = 78.07 g/mol

Volume  = 1.0 L

Solution:

Molarity = given mass÷ molar mass) × (1 ÷ vol (L) )

     Molarity  = (27.5 ÷ 78.07)× (1 ÷ 1) = 0.352 M
