NEET · Chemistry · STD 12 -1. Solution and colligative properties
In water saturated air the mole fraction of water vapour is \(0.02\). If the total pressure of the saturated air is \(1.2\; atm\), the partial pressure of dry air is .....\(atm\)
- A \(1.21\)
- B \(1.76\)
- C \(1.17\)
- D \(0.98\)
Answer & Solution
Correct Answer
(C) \(1.17\)
Step-by-step Solution
Detailed explanation
