Answer:

#M=2.0# #mol# #L^-1#

Explanation:

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

#M=n/V#

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=n/V#

#M=4.0/2.0# #mol# #L^-1#

#M=2.0# #mol# #L^-1# or #M=2.0# #mol# #dm^-3# if the questions mention volume of solution in #dm^3# because #L=dm^3#
