3) A solution was made by dissolving 700 g of Na2SO4 in 0.5 kg of H2O. Calculate the mole fraction of Na2SO4. The molar mass of Na2SO4 is 142.05 g/mol. 4) Mrs. Alvarez assigned you to prepare a solution of 2.44 molal H2SO4 solution. What mass of H2SO4 in grams, you must be dissolved to .180 kg H2O to produce the desired molal solution? MM of H2SO4 is 98.8 g/mol
