Question

What is the mass of 0.5 mole of ozone molecule?
(A) 8 g
(B) 16 g
(C) 24 g
(D) 48 g

Answer 1

mass of 1 mole of ozone molecule is 48g.
so now we can find the mass of
0.5 mole of ozone that is 48/2=24

Answer 2

Hii Sushila,

● Answer -
(C) 24 g

◆ Explanation -
Atomic mass of oxygen is 16.
One ozone molecule contains 3 O-atoms. So molecular weight of ozone would be 16×3 = 48 g/mol.

Hence, 0.5 mole of ozone weighs -
W = n × M
W = 0.5 × 48
W = 24 g

Therefore, weight of 0.5 mol of ozone is 24 g.


Hope this helped you. Thanks for asking..
