Answer:

27.3%

Explanation:

Mass of CO2 =44gm

Mass of C in CO2=12gm

Answer 2

Hi mate !!

here is ur answer -

so we multiply 2 with 16.00 which is the weight of oxygen . This is the total weight of the CO2. Now, to know the percent composition of Carbon and Oxygen . We will divide their weight with total weight of CO2. % C=12.01/44.01=0.2729= 27.29%

( we will divide 0.2729 with 100 to take the percentage .)

hope it helps you !
