Question

what is the persentage of oxygen in carbon dioxide

Answer 1

72.71% of oxygen is their in Carbon dioxide.
While, 27.29% carbon is their in Carbon dioxide.
% C = 12.01/44.01 = 0.2729= 27.29%

So , % C in CO2 is 27.29%

% O = 32.00/44.01 =0.7271 =72.71 %O in CO2.

Answer 2

Answer:72.7 %Explanation:The formula for percent composition is:-Percentage composition = Mass of O2/Mass of CO2 *100So mass of O2 = 2Atomic Wt. of oxygen = 216 = 32And mass of CO2 = Atomic Wt of Carbon + 32 = 12 + 32 = 44Therefore, punching in the masses in the above formula we get-
Percentage composition = 32/44 * 100 = 72.7 % (Answer)
