Question

What is the ratio between masses of carbon and oxygen in CO2?

[Atomic mass of C=12u,O=16u]​

Answer 1

Answer:

3:8

Explanation:

carbon = 12

oxygen = 16 (O2 = 2× 16)

carbon/oxygen = 12/32

C:O = 3:8

Answer 2

Answer:

Mass of carbon=12u

Mass of oxygen=2×16u

Therefore ratio=Carbon/Oxygen

12u/32u=3:8
