Question

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

Answer 1

Answer:

hey mate,

molecular weight of co2= 44gm

12gm of carbon is present in 44gm of co2

so the percentage of carbon in co2 =12/44 × 100

=27%

32gm of oxygen is present in 44gm of co2

so the percentage of oxygen in co2=32/44 ×100

=73%
