Question

8. Which one will have the maximum number of Oxygen atoms?

(a) 32 molecules of O2

(b) 3.2 grams of O2

(c) 32 grams of O2

(d) 2 moles of O2


ANSWER FAST I HAVE EXAM

Answer 1

Answer:

(a) The mass of 1 mole of oxygen

atoms = 16 g

Thus, the mass of 0.2 mole of

oxygen atoms = 16 * 0.2 = 3.2 g

b) The mass of 1 mole of water

molecules = 18 g

Thus, the mass of 0.5 mole of

water molecules = 18 × 0.5 = 9.0 g

Answer 2

Answer:

The mass of 1 mole of oxygen atoms = 16 g

The mass of 1 mole of oxygen atoms = 16 gThus, the mass of 0.2 mole of oxygen atoms = 16 × 0.2 = 3.2 g

B . is the correct option 3.2grams of O2
