-to calc -unit of molality is mol/kg
Select all the statements that correctly describe the molality and molarity of a solution
M must be calculated both molarity and molality express
Match each concentration term with the correct ratio each represents.
M= mol of solute/ L m= mol of solute/kg percen= 100% fraction(x)= mol/ #
