You HAVE TO know that molarity (M) tells you the number of moles of a solute per Liters of solution.
M=mol/L
0.3M = 2.7 mol/ Volume
Volume = 2.7 mol/3.0 L
Volume = 0.9 L

Answer: The volume of the solution is 9 L.

Explanation:

Molarity is defined as the number of moles present in one liter of solution.

Mathematically,

[tex]\text{Molarity of the solution}=\frac{\text{Moles of solute}}{\text{Volume of solution (in L)}}[/tex]

We are given:

Moles of solute = 2.7 moles

Molarity of the solution = 0.3 moles/ L

Putting values in above equation, we get:

[tex]0.3mol/L=\frac{2.7}{\text{Volume of solution}}\\\\\text{Volume of the solution}=9L[/tex]

Hence, the volume of the solution is 9 L.
