Question

What is the percentage of carbon in co2?

Answer 1

Answer:

Carbon dioxide/Carbon content (%)

27.3%

Explanation:

part/whole x 100

1 carbon= 12.0 g

2 oxygen= 32.0 g

1 carbon + 2 oxygen (CO2) = 44.0 g

12.0g/44.0g x 100= 27.3% C in CO2 gas

Answer 2

Answer:

27.3% by mass,

33.33% by atom count

Explanation:

Molecular formula of carbon dioxide is CO 2

​

.Molar mass of carbon dioxide is 12+2(16)=44 g/mol.

Mass percentage of carbon in carbon dioxide is  

44/12 ×100=27.27%.

=which can be 27.3%
