Water is added in excess to a 100g sample labelled as 112%H2SO4 This solution is then treated with 5.3g of Na2CO3. the volume of CO2 evolved at 1atm and 300K after a complete reaction will be : H2SO4+Na2CO3→Na2SO4+H2O+CO2

Solution
The correct option is C 1.27 L 112%H2SO4 means water is in excess and the mass of H2SO4 112 g
Reaction : H2SO4+Na2CO3→NaSO4+CO2+H2O
number of mole of H2SO4=112/98
number of mole of Na2CO3=5.3/106=0.05 Na2CO3 is limiting reagent so 0.05 moles of CO2 produced at STP which volume is eqaul to 1.27 L
