Question

116 g of a substance upon dissociation reaction, yields 7.5 g of hydrogen, 60 g of oxygen and 48.5 g of carbon. Given that the atomic masses of H , O and C are 1,16 and 12 respectively. The data agrees with how many formulate of the following?

TestHub · Accepted Answer

% H = 116 7.5 ​ × 100 = 6.5 % O = 116 60 ​ × 100 = 51.7 % C = 116 48.5 ​ × 100 = 41.8 Relative atomicities = H ⇒ 6.5 O ⇒ 16 51.7 ​ = 3.25 C ⇒ 12 41.8 ​ = 3.5 Emperically formula is approx.. CH 2 ​ O (A) C 2 ​ H 4 ​ O 2 ​ (B) CH 2 ​ O relate to this formula.
