Question

A 0.420 M Ca(OH)2 solution was prepared by dissolving 64.0 grams of Ca(OH)2 in enough water. What is the total volume of the solution formed?
1.07 liters

1.23 liters

2.05 liters

2.18 liters

Answer 1

Answer:
2.05 liters

Calculate the molar mass of Ca(OH)2 =74.09g/mol

Calculate how many mol of Ca(OH) are in 64g

n=m/MM
n=64/74.09
n=0.86 mol

Calculate the volume of solution
M=n/V => V=n/M

V= 0.86 mol/ 0.420M
V= 2.05 liters

Answer 2

Answer:

C) 2.05 liters is the CORRECT ANSWER!
