JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
If a rocket runs on a fuel \(\left( C _{15} H _{30}\right)\) and liquid oxygen, the weight of oxygen required and \(CO _{2}\) released for every litre of fuel respectively are: (Given: density of the fuel is \(0.756\, g / mL\) )
- A \(1188 \,g\) and \(1296 \,g\)
- B \(2376 \,g\) and \(2592 \,g\)
- C \(2592\, g\) and \(2376 \,g\)
- D \(3429\, g\) and \(3142 \,g\)
Answer & Solution
Correct Answer
(C) \(2592\, g\) and \(2376 \,g\)
Step-by-step Solution
Detailed explanation
\(C _{15} H _{30}+\frac{45}{2} O _{2} \rightarrow 15 CO _{2}+15 H _{2} O\) Mass of fuel \(=0.756 \times 1000 \,g\) No. of moles of fuel \(=\frac{0.756 \times 1000}{210}\) Wt. of oxygen \(=\frac{0.756 \times 1000}{210} \times \frac{45}{2} \times 32=2592 \,g\) Wt of…
