Question

14. Assertion (A): Molecular mass of Carbon dioxide (CO2) is 44g.
Reason (R) Atomic mass of a carbon atom is 12g and atomic mass of an
oxygen atom is 14g
​

Answer 1

Answer:

Atomic mass of carbon atom is 12g and atomic mass of oxygen atom is 32g in CO2.

Explanation:

Total mass of CO2 = 44g

atomic mass of oxygen = 16

A/Q

oxygen = 16×2 = 32g

carbon = 12×1 = 12g

Total mass = 44g
