Question

calculate the percentage
of oxygen in CO2 C = 12u and o =16u​

Answer 1

Answer:

Molecular weight of CO2 is 44grams is [12+(2*16)]

12 grams of carbon are present in 44 grams of carbon dioxide

Thus, percentage weight of carbon in CO2= 12/44*100=27.27%

percentage weight of oxygen in CO2= 32/44*100 =72%

so

percentage weight of carbon and oxygen in CO2 = 22.27% and 72%
