Answer 1

Answer:

Hey guys follow me

Explanation:

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

Answer 2

hey mate here is your answer..

ans=Molecular mass of CO2 =1×12 + 2×16 = 44 g
1 g molecule of CO2 contains 1 g atom of carbon
44 g of CO2 contains C = 12 g of carbon
% of C in CO2 = 12/44 x 100 =27.27%
Hence, the mass per cent of carbon in CO2 is 27.27%.

hope this helps you
