Question

Carbon dioxide is % carbon and % oxygen.

Answer 1

Answer:

Explanation:

To know the per cent 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 0.2729 with 100 to take the percentage).

% O = 32.00/44.01 = 0.7271

= 72.71 %O in CO2.
