Options
- A. 4.07 \% and 15.02 \%
- B. 18.18 \% and 3.70 \%
- C. 15.02 \% and 4.07 \%
- D. 3.70 \% and 18.18 \%
Answer
B. 18.18 \% and 3.70 \%
Step-by-step solution
Percentage of carbon = 12 m _2 100 44 m m = mass of organic compound =0.3 ~g m _2= mass of carbon dioxilde =0.2 ~g \% C= 12 0.2 100 44 0.3 =18.18 \% Percentage of hydrogen = 2 m _1 100 18 m m _1= mass of water =0.1 ~g \% H = 2 0.1 100 18 0.3 =3.70 \%
