Some Basic Concepts Of Chemistry Question 195

Question: A gaseous mixture contains $C H_{4}$ and $C_{2} H_{6}$ in equimolecular proportion. The weight of 2.24 litres of this mixture at NTP is

Options:

A) 4.6 g

B) 1.6 g

C) 2.3 g

D) 23 g

Show Answer

Answer:

Correct Answer: C

Solution:

Equimolecular proportion means both gases occupied equal volume $= \frac{2.24}{2} = 1.12 L$

For $C H_{4}$ : 22.4L $C H_{4}$ has mass $= 16 g m$

1.12L $C H_{4}$ has mass $= \frac{16}{22.4} \times 1.12 = 0.8 g m$ . For $C_{2} H_{6}$

22.4L $C_{2} H_{6}$ has mass = 30gm 1.12L $C_{2} H_{6}$ has mass $= \frac{30}{22.4} \times 1.12$ $= \frac{3.0}{2} g m = 1.5 g m$

Total mass $= 1.5 g m + 0.8 g m = 2.3 g m$ .
