Answer 1

Molarity is a concentration term that expresses the strength of a solution in terms of the ratio of number of moles of solute to the volume of solution in litres.Its unit is ''M'' or '' mol L^-1.

Since ,volume of solution is not provided, we need to obtain it using the density formula.

Density of solution = mass of solution/ volume of solution

Make it a practice to give units appropriately after every numerical value.
