Question

How to calculate percentage composition of carbon dioxide?​

Answer 1

Answer:

Mass of carbon dioxide [CO

2

]

=1(C)+2(O)

=1(12)+2(16)

=12+32=44

% mass of carbon =

44

12

×100=21.3%

% mass of oxygen =

44

32

×100=72.7%

Answer 2

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 0.2729 with 100 to take the percentage). % O = 32.00/44.01 =0.7271 =72.71 %O in CO2.0
