Answer» ANSWER : plz MARK as brainliest Explanation:No. of oxygen atoms in one molecule =4+10=14 *THUS MOLES of oxygen in n moles of compound=n14 Molar mass of Na2SO4.10H2O=46+32+64+180=322g/mol Thus 32.2g=32.2/322=0.1 mols Thus moles of O=0.114=1.4* So weight is *161.4=22.4g**

ANSWER : plz MARK as brainliest

Explanation:No. of oxygen atoms in one molecule =4+10=14

THUS MOLES of oxygen in n moles of compound=n*14

Molar mass of Na2SO4.10H2O=46+32+64+180=322g/mol

Thus

32.2g=32.2/322=0.1 mols

Thus moles of O=0.1*14=1.4

So weight is

16*1.4=22.4g
