What is meant by the term chemical formula?Write the chemical formula of calcium carbonate carbonate. Calculate its formula unit mass. (Atomic mass of

Ca=40u, C=12u, O=16u)


Chemical formula is the symbolic representation of the composition of the compound.from it , we can know the no: and different kinds of different elements that constitute the compound.

the chemical formula is CaCo3
formula unit mass of calcium carbonate 
= atomic mass of calcium+ atomic mass of carbon + 3 
× atomic mass of oxygen
= 40u + 12u +  ( 3 × 16u ) = 100u
0 0 0
Chemical formula is a set  of chemical symbols showing the elements present in a compound and their relative proportions
formula of calcium carbonate = CaCO3
Atomic mass = 40+12+16*3
