Cement is a maxture of calcium and aluminium silicates, formed by heating limestom with clay.
4CaCO3(s) + Al, S1,0,(s) - 2CASIO (s) + Ca AlO3(s) + 4CO2(g)

cement
A typical bag of cement has a mass of 25 kg. Calculate the mass of limestone (taken
calcium carbonate) required to make 25 kg of cement.
The moler mass of cement, taken as (2Casioz + C2 ALO). Is 446.6 gmor
