Answer 1

Answer:

$\underline{\huge{\texttt{22.4g}}}$

Explanation:

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

Thus moles of oxygen in n moles of compound $\:=n\times14$

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

Thus

$32.2g=32.2/322=0.1 mols$

Thus moles of $O=0.1\times14=1.4$

So weight is  

$16\times1.4=22.4g$
