The molecular weight of Na₂SO₄.10H₂O is 322 amu.
So 1 mole of Na₂SO₄.10H₂O has a mass of 322 grams.
In 1 mole of it there are 14 oxygen atoms with mass 224 grams.
1.61 grams means 0.005 moles of Na₂SO₄.10H₂O
1 mole has 224 grams of oxygen then,
0.005 moles have (0.005 x 224) grams of oxygen.
= 1.12grams
hope it help
