Calculate the volume of co2 at stp obtained by heating 25g of caco3

1.	Calculate the volume of co2 at stp obtained by heating 25g of caco3
Answer» HERE IS YOUR ANSWER CaCO3 molar mass is 100 u. or it can be represented as 100 grams when it is EXPRESSED as molecular mass. CaCO3 ---------> CaO + CO2 CO2 molar mass is 44 u, it's molecular mass is 44 grams. This implies 100 g of CaCO3 gives 44 g of CO2. Therefore 25 g of CaCO3 gives 44/100 * 25 = 11 grams. One MOLE of CO2 is 44 grams. Therefore in 11 grams of CO2 , there would be 1/44 * 11 = 0.25 moles. one mole of CO2 occupies 22.4 L of VOLUME, therefore 0.25 moles of CO2 has a volume of 22.4 * 0.25 = 5.6 L of volume. THANK YOU
