0.765 gm of acid gives 0.55 g of CO₂ and 0.12 g of H₂O.Then find the ratio of the percentage of carbon and hydrogen
Options
(a) 19 : 2
(b) 18 : 11
(c) 20 : 1.7
(d) 1 : 7
Correct Answer:
20 : 1.7
Explanation:
44g of CO₂ contains 12 g carbon. Therefore 0.55 g of CO₂ contains 12/44×0.55 , 0.15 g carbon. 18 g of H₂O contains 2 g hydrogen, Therefore 0.12g of H₂O contains 2/18×0.12, 0.013 g hydrogen. Percentage of carbon = 0.15/0.765×100=19.6=w. Percentage of hydrogen = 0.013/0.765×100=1.7. Ratio of percentage of C and H is 20 : 1.7.
