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.

Respuesta :

Answer:

766mL

Explanations:

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

[tex]\begin{gathered} molarity=\frac{moles}{volume} \\ \end{gathered}[/tex]

Given the following parameters

moles of NaH = 1.67moles

molarity of solution = 2.18M

Substitute to determine the volume

[tex]\begin{gathered} volume=\frac{moles}{molarity} \\ volume=\frac{1.67}{2.18} \\ volume=0.766L=766mL \end{gathered}[/tex]

Hence the volume of the solution in mL is 766mL
