Question

14) Calculate the volume (in mL) of a solution that contains 1.67 moles of NaH if the concentration ofthis solution is 2.18 M NaH. Enter your answer using 3 significant figures.

Answer 1

766mL

Explanations:

The formula for calculating the molarity of a solution is expressed as:

`\begin{gathered} molarity=(moles)/(volume) \\ \end{gathered}`

Given the following parameters

moles of NaH = 1.67moles

molarity of solution = 2.18M

Substitute to determine the volume

`\begin{gathered} volume=(moles)/(molarity) \\ volume=(1.67)/(2.18) \\ volume=0.766L=766mL \end{gathered}`

Hence the volume of the solution in mL is 766mL
