Question

if carbon dioxide is 33 what is the ratio of carbon and oxygen

Answer 1

Molar mass of CO₂ = 44g contains 12g oxygen and 32g oxygen, so ratio = 3 : 8

But in 33g of CO₂, amount of carbon = (12 * 33) / 44 = 9g

In 33 g of CO₂, amount of oxygen = ( 32 * 33) / 44 = 24g

So ratio of C and O in 33g of CO₂ = 9 / 24 = 3 : 8

So either in 44g or 33g of CO₂ ratio of Carbon and oxygen are same = 3 : 8.
