Question

A sulphuric acid solution containing 571.4 gram of H2SO4 per litre of the solution has a density of 1.329 gram per centimetre cube. Calculate the molality, molarity and mole fraction of H2SO4 in this solution. ​

Answer 1

Explanation:

H2SO4

H2SO4mass of the solution = d x V = 1.329 x 1000 = 1329 g

H2SO4mass of the solution = d x V = 1.329 x 1000 = 1329 g%C = mass solute / d V x(100)

H2SO4mass of the solution = d x V = 1.329 x 1000 = 1329 g%C = mass solute / d V x(100)The mass % for the density of the solution does not correspond

H2SO4mass of the solution = d x V = 1.329 x 1000 = 1329 g%C = mass solute / d V x(100)The mass % for the density of the solution does not correspondto 1.329 g/mL (density) it corresponds to 35.9%

H2SO4mass of the solution = d x V = 1.329 x 1000 = 1329 g%C = mass solute / d V x(100)The mass % for the density of the solution does not correspondto 1.329 g/mL (density) it corresponds to 35.9%m =%CDV

H2SO4mass of the solution = d x V = 1.329 x 1000 = 1329 g%C = mass solute / d V x(100)The mass % for the density of the solution does not correspondto 1.329 g/mL (density) it corresponds to 35.9%m =%CDVm = 0.359 x 1.329 x 1000 mL = 477.11 (mass solute)

H2SO4mass of the solution = d x V = 1.329 x 1000 = 1329 g%C = mass solute / d V x(100)The mass % for the density of the solution does not correspondto 1.329 g/mL (density) it corresponds to 35.9%m =%CDVm = 0.359 x 1.329 x 1000 mL = 477.11 (mass solute)477.11/98 g/mol = 4.87 mol

4.87 mol/1 L = 4.87 M
