How much CaCO3 do you have? That's 20 g x (1.00 - 0.20) = 16
CaCO3 ==> CaO + CO2
mols CaCO3 = 16/molar mass CaCO3 = ?
mols CaCO3 = mols CO2 from the equation.
mols CO2 x 24 L/mol @ NTP.
OR you can use 22.4 L/mol @ STP and convert to NTP by correcting for the T from 273.15K to 293.15 K. I have estimated the 24 number above.
Post your work if you get stuck.
What volume of carbon dioxide gas is produced at NTP when 20gram of 20percent pure caco3 is completely heated
