Question

How much litre of Co2 is released up heating 350 gram of caco3

Answer 1

Explanation:

CaCO3 =>CaO + CO2

So on heating one mole of CaCO3 we get one mole of CaO and CO2. Hence 1 mole of CaCO3 weighs (40+12+3×16) => 100 gms. So no. of moles present in 350 gms of CaCO3 => 350/100 =>3.5 Hence no. of moles of CO2 obtained =>3.5. So the volume of CO2 released => 3.5×22.4 as 1 mole of a gas occupies 22.4 litres at STP => 78.4 litres. Hope it helps you.
