Question

Calculate atomicity of (a) H2O (b) CaCO3​

Answer 1

Answer:

a--34 and b--100 is the correct answer mark me as brainiest

Answer 2

Answer:

a) It can be determined as a ratio of molecular mass and atomic mass. For example, using thecase of oxygen molecule, the molecular mass is 32 (= 2x16), while the atomic mass is 16. If we divide the two, we get atomicity as 2 (=32/16).

b)5

The formula of Calcium Carbonate is CaCO3. Atomicity is defined as the number of atoms present in the molecule of a compound . CaCO3 is made up of 1 atom of calcium , 1 atom of carbon and 3 atoms of oxygen . Thus , Atomicity of Calcium Carbonate is 5.
