Question

what is mass percent of carbon in CO2??​

Answer 1

So, we will multiply 2 with 16.00 which is the weight of the oxygen. This is the total weight of CO2. Now, to know the percent composition of Carbon and Oxygen .We will divide their weight with the total weight of CO2. % C = 12.01/44.01 =0.2729= 27.29% (we will divide 0.2729with 100 to take the percentage).

Answer 2

Heyaa !!!
.
.
hers a happy answer to ur question :-)

CO2 (carbon dioxide.)contains one atom of carbon and two atom of oxygen .

therefore
mass percentage of oxygen :- 72.7 percent .
mass percentage of carbon :- 27.3 percent .

Therefore the 100 percent of CO2 (carbon dioxide.) :-

72.7+27.3 = 100
