Answer 1

The given question is incomplete. the complete question is:

Calculate the volume in liters of a 0.91 M magnesium fluoride solution that contains 249.2 g of magnesium fluoride . Round your answer to 2 significant digits.

Answer: 4.4 Liters

Explanation:

Molarity of a solution is defined as the number of moles of solute dissolved per liter of the solution.

$Molarity=\frac{n}{V_s}$

where,

n = moles of solute

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{249.2g}{62.3g/mol}=4.00moles$

$V_s$ =volume of solution in L

$0.91=\frac{4.00}{V_s}$

Thus the volume in liters is 4.4 L
