Answer:

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).

Answer 2

Answer:

Molecular formula of carbon dioxide is CO2

Molar mass of carbon dioxide is 12+2(16)=44 g/mol.

Mass percentage of carbon in carbon dioxide is

$\frac{12}{44} \times 100$

$= 27.27\%$
