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.
[tex]Molarity=\frac{n}{V_s}[/tex]
where,
n = moles of solute
To calculate the moles, we use the equation:
[tex]\text{Number of moles}=\frac{\text{Given mass}}{\text{Molar mass}}=\frac{249.2g}{62.3g/mol}=4.00moles[/tex]
[tex]V_s[/tex] =volume of solution in L
[tex]0.91=\frac{4.00}{V_s}[/tex]
Thus the volume in liters is 4.4 L
