Question

calculate the mass of 2 moles of oxygen atom

Answer 1

$\huge\fcolorbox{red}{cyan}{32g}$

Explanation:

• Atomic Mass of Oxygen = 16u

Therefore Gram Atomic Mass = 16 g

By Mole Concept :-

1 mole = 16 g of Oxygen

Therefore :-

$1 mole = 16 g of oxygen \\ => 2 mole = 2 \times 16 \\ => \boxed{32}$

Hope it helped

Answer 2

mass of 1mole oxygen atom is 16g

mass of 2 mole of oxygen atom is 16×2 = 32 g
