Answer 1

Hello.....

Simply, 1 mole of (COOH)2.2H2O has 6 moles of Oxygen atoms. (adding them up)

therefore by using unitary method, if 1 mole contain 6 mole O atoms, 0.3 moles will contain 0.3×6 moles of atoms , I.e. 1.8 moles of Oxygen atoms.

NOTE - GRAM ATOM, GRAM MOLECULE, GRAM MOLES are all MOLES.
