Question

how many gram of H2O are present in 0.3 mole of it​

Answer 1

Answer:

Hence, the number of gram atoms of oxygen present in 0.3 moles of oxalic acid dihydrate is 0. 3×6=1. 8 .

Answer 2

Answer:

ANSWER

One molecule of oxalic acid dihydrate contains six oxygen atoms.

Thus, one mole of oxalic acid dihydrate will contain six gram atoms of oxygen atoms.

Hence, the number of gram atoms of oxygen present in 0.3 moles of oxalic acid dihydrate is 0.3×6=1.8 .
