Question

The ratio of carbon and oxygen in a sample of carbon dioxide is 3:8. What is the mass of carbon in a sample of 4g of carbon dioxide?

Answer 1

Given :

The ratio of carbon and oxygen in carbon dioxide = 3 : 8

Mass of the carbon dioxide in the sample = 4 g

To find :

The mass of the carbon in the sample .

Solution :

Mass of the carbon in the sample = [ 3 / ( 3 + 8 )] * 4 g

=> mass of the carbon in the sample = 12 / 11 g = 1.09 g (approx.)

The mass of the carbon in the sample is 1.09 g approximately .
