A 10.0% by mass H2SO4 (aq) solution has a density of 1.07 g/mL. How many milliliters of solution contain 8.37 g of H2SO4? What is the molality of H2SO4 in solution? What mass (in grams) of H2SO4 is in 250 mL of solution?

Solutions

Expert Solution

10% H2So4 means 10g of H2SO4 present in 100g of solution

volume of solution = mass/density

                               = 100/1.07

                               = 93.46ml

10g of H2SO4 present in 93.46ml of solution

8.37g of H2So4 present in = 93.46*8.37/10    = 78.23ml of solution

mass of solvent = mass of solution - mass of solute

                            = 100-10 = 90g

molality      =   W*1000/G.M.Wt*weight of solvent in g

                   = 10*1000/98*90

                   = 1.134m >>>>>>>>answer

93.46ml of solution contains 10g of H2SO4

250ml of solution contains = 10*250/93.46    = 26.75g of H2So4
