Carbon dioxide is a gaseous molecule made up of the elements, C and O. Each mole of carbon dioxide has one mole C and two mole oxygen atoms.
Molar mass of carbon dioxide ([tex]CO_{2}[/tex])=[tex](1 * 12.01\frac{g}{mol}) +(2* 16\frac{g}{mol})=44.01\frac{g}{mol}[/tex]
Percentage by mass of carbon = [tex]\frac{(1*12.01\frac{g}{mol}) }{44.01\frac{g}{mol} } *100=27.3%[/tex]
Percentage by mass of oxygen = [tex]\frac{(2*16\frac{g}{mol})}{44.01\frac{g}{mol} } *100=72.7%[/tex]
Therefore C is 27.3 % and O is 72.7 % by mass in 1 mol CO[tex]_{2}[/tex]
Carbon dioxide is 27.3% in carbon and 72.7% in oxygen.
Percent composition tells you by mass what percent of each element is present in a compound
We will calculate the mass percent (%Elem) of each element using the following expression.
%Elem = (mElem / mComp) × 100%
where,
%C = (12.01 g / 44.01 g) × 100% = 27.3%
%O = (2 × 16.00 g / 44.01 g) × 100% = 72.7%
Carbon dioxide is 27.3% in carbon and 72.7% in oxygen.
