Calculate the mass percent (m/m)(m/m) of a solution containing 14.5 g of Na2SO4 and 76.5 g of H2O.
Here we know that formula of mass % is
(Mass of solute/ Mass of solution)*100
Therefore it is given that 14.5 g of Na2So4 dissolved in 76.5g of H20.
Mass % of Na2So4(solute) is
(14.5/14.5+76.5)*100 = 15.93%
Mass % of H20 in soln will be
(76.5/14.5+76.5)*100= 84.06%
