Question

What is the mass of
a) 0.2 mole of Sulphur atoms.
b) 2 moles of water molecules.

Answer 1

Solution

Verified by Toppr

(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:

(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) I am giving an image
