Question

C+ 2H2SO4-----> CO2+ 2H2O+ 2SO2
Calculate:
1. The volume of sulphur dioxide measured STP, liberated at the same time.( volume occupied by one mole of a gas at STP is 22.4 dm3 )

Answer 1

reaction tells us that if 1mol CO2 is released then,

2mol sulphur dioxide is released.

so just multiply number of moles of sulphur dioxide with 22.4dm3(1dm3=1000cm3)

hope this will help you
