Some Basic Concepts Of Chemistry Question 255
Question: If isobutane and n-butane are present in a gas, then how much oxygen should be required for complete combustion of 5 kg of this gas
Options:
A) 17.9 kg
B) 9 kg
C) 27 kg
D) 1.8 kg
Show Answer
Answer:
Correct Answer: A
Solution:
Isobutane and n-butane $ [ C _4H _{10} ] $ have same molecular formula; $ C _4H _{10}+\frac{13}{2}O _2\to 4CO _2+5H _2O $
For 58gm of $ C _4H _{10} $ 208 gm $ O _2 $ is required then for 5 kg of $ C _4H _{10} $ $ O _2=\frac{5\times 208}{58}=17.9,kg $
