i hope this helps u bro.

Answer 2

Question :-

What is the mass of :

(a) 0.2 mole of oxygen atoms?

(b) 0.5 mole of water molecules?

Answer :-

(a) Mole of Oxygen atoms = 0.2 mole

Molar mass of oxygen atoms = 16 g

Mass of oxygen atoms = 16 x 0.2 = 3.2 g

(b) Mole of water molecule = 0.5 mole

Molar mass of water molecules = 2 x 1 + 16= 18 g .

Mass of H2O = 18 x 0.5 = 9 g
