If 0.31 mol of #Na_2SO_4# dissolve in water to make 740 mL of solution, how would you find the molarity of the resulting solution? Chemistry Solutions Molarity 1 Answer anor277 Mar 4, 2017 Answer: #"Molarity"="Moles of solute"/"Volume of solution"# Explanation: And thus for the molarity of the given solution, we have: #(0.31*mol)/(740*cancel(mL)xx10^-3*L*cancel(mL^-1))=0.42*mol*L^-1# with respect to #Na_2SO_4#.
