no.of moles of CaCO3 = 50/100 = 0.5

according to reaction 1 mole of CaCO3 gives 1 mole of CO2

so 0.5 moles of CaCO3 will give 0.5 moles of CO2

now at STP 1 mole of any gas = 22.4 L

so 0.5 moles of CO2 gas = 22.4 X 0.5 = 11.2 L

The main components of egg shell is CaCo3.if 25cm cube of 0.700mol/m cube Hcl reacted with all CaCo3 in a sample of egg shells. Calculate the mass of CaCo3 in the egg shell and the volume of Co2 evolved at STP.
