An acidic solution is 0.1M in HCl and 0.2 H2so4. volume is equal to no of moles divided by molarity.

number of moles of HCl is 450ml x 0.1 divided by 1000 which is equal to 0.045 moles

volume of HCl is therefore 0.45 divided by 0.16 which is 2.81 litres

Number of moles of H2so4 is 450ml x 0.2 divided by 1000 which is equal to 0.09 moles

volume of H2SO4 IS 0.09 divided by 0.16 which is equal to 0.56 litres
