MHT CET · Chemistry · Some Basic Concepts of Chemistry
The vapour density of a certain gas is 16. What is the volume occupied by 8 g of gas at STP assuming ideal behaviour?
- A \(2.80 \mathrm{~dm}^3\)
- B \(5.6 \mathrm{~dm}^3\)
- C \(11.2 \mathrm{~dm}^3\)
- D \(2 \cdot 24 \mathrm{~dm}^3\)
Answer & Solution
Correct Answer
(B) \(5.6 \mathrm{~dm}^3\)
Step-by-step Solution
Detailed explanation
\( M = 2 \times 16 = 32 \mathrm{~g/mol} \) \( n = \frac{8 \mathrm{~g}}{32 \mathrm{~g/mol}} = 0.25 \mathrm{~mol} \)
