The percentage we can calculate by formula: W(E) = n*Ar (E)/Mr (substance) where W(E) - the percentage of element n - amount of element in substance Ar (E) - atomic weight of element Mr (substance) - molecular weight of substance Mr (substance) = 12*6+1*10+16*4 = 146 amu W(C) = 6 * 12/ 146 = 0.493 * 100 % = 49.3% W(H) = 1 * 10/ 146 = 0.0684 * 100 % = 6.84% W(O) = 16 * 4/ 146 = 0.438 * 100 % = 43.8%Answer: W(C) = 49.3%, W(H) = 6.84%, W(O) = 43.8%
