\(\mathrm{x} \mathrm{g}\) of methane was burnt completely in the presence of oxygen. The liberated gases were passed into a solution containing \(370 \mathrm{~g}\) of \(\mathrm{Ca}(\mathrm{OH})_2\). The weight of white precipitate obtained was 500 . What is the value of \(x\) (in g)?
(Given : \(\mathrm{C}=12 ; \mathrm{H}=1 ; \mathrm{Ca}=40 ; \mathrm{O}=16 \mathrm{u}\) )
- A 16
- B 80
- C 160
- D 120
Answer & Solution
Correct Answer
(B) 80
Step-by-step Solution
Detailed explanation
\(\mathrm{CH}_4+2 \mathrm{O}_2 \rightarrow \mathrm{CO}_2+2 \mathrm{H}_2 \mathrm{O}\) Thus, 1 mole of \(\mathrm{CH}_4\) gives 1 mole of \(\mathrm{CO}_2\) gas. \(\mathrm{CO}_2\) gas combines with \(\mathrm{Ca}(\mathrm{OH})_2\) as :-…
