Question

Teh number of gm of oxygen present in32.2 gm of na2so4.10h2o will be

Answer 1

Explanation:

Number of gm of oxygen in 32.2 g na2so4.10h2o is No. of oxygen atoms in one molecule =4+10=14. ... Molar mass of Na2SO4.10H2O=46+32+64+180=322g/mol. ... 32.2g=32.2/322=0.1 mols32.2g=32.2/322=0.1mols.

Answer 2

Explanation:

Since the

number of gm of oxygen present in32.2 gm of na2so4.10h2o will be 32.2 gm compound will contain 1.4 gm Oxygen ... molecular mass of Na2SO4.10H2O =322 gm
