Question

what is the mass percent of carbon in carbon dioxide

Answer 1

So, 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.

Answer 2

Hey user !!!

Here,, The molar mass of CO2= 44 u

But ,, IN CO2 The carbon present = 12 u

Theirfore,, The requried mass percent of carbon in CO2 = 12÷44×100= 27.7 %
