Question

If 0.0369 mol CaCl2 is dissolved in water to make a 0.340 M solution, what is the volume of the solution

Answer 1

Answer:

The correct answer is 0.11 L

Explanation:

From the problem, we have the following data:

moles CaCl₂= 0.039 mol

molarity = 0.340 M = 0.340 mol CaCl₂/L

According to this, the solution has 0.340 mol of CaCl₂ in 1 L. If the total number of moles is 0.0369, we can find the volume as follows:

V= moles/molarity = 0.0369 mol x 1 L/0.340 mol = 0.108 L ≅ 0.11 L
