Question

Calculate the mass percentage of carbon, oxygen in carbon
dioxide?​

Answer 1

Answer:

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 divide0.2729 with 100 to take the percentage.

Explanation:

Answer 2

Answer:

to calculate mass percent og carbon just do it...

CO2 -> its molecular mass is 44g

now calculate for Carbon..

12/44 x100

=0.27=27% C

now for oxygen

16x2/44 x100

=0.72=72% O2
