Question

Calculate the mass of Carbon and oxygen in 330g of carbon dioxide (CO2).

Answer 1

Answer:

C = relative atomic mass of Carbon => 12.01

O2 = Oxygen (two atoms) = 16.00 x 2 = 32.00

CO2 total relative atomic mass = 44.01

%C in CO2 = 12.01/44.01 = 27.29%

%O in CO2 = 32.00/44.01 = 72.71%

Grams C in 5 grams CO2 = 5*(0.2729) = 1.364 g

Grams O (as O2) in CO2 = 5*(0.7271) = 3.636 g
