M=2.0 mol L1

Explanation:

The molarity, M of this solution can be calculated by a formula which is;

M=nV

where;
M= Molarity of solution
n=Number of moles of solute
V= Volume of solution in Litre

Given, n=4.0 moles and V=2.0 L, so we have enough information to calculate the molarity of the solution;

M=nV

M=4.02.0 mol L1

M=2.0 mol L1 or M=2.0 mol dm3 if the questions mention volume of solution in dm3 because L=dm3
