Question

Calculatethe percentage composition of carbon and oxygen in CO2

Answer 1

Answer:

1:8

Explanation:

atomic mass of carbon: 12

atomic mass of oxygen: 16

in the formation of CO2 we have 1 atom of carbon (12) and 2 atoms of oxygen (2x16)

hence in CO2 the composition is 12:32=1:8

for percentage composition

=1/8x100

=12.5%
