2. | \(\mathrm{p}=\mathrm{p}_{1}+\mathrm{p}_{2}+\mathrm{p}_{3} \) |
3. | \(\mathrm{p}=\mathrm{n}_{1} \frac{\mathrm{RT}}{\mathrm{V}}+\mathrm{n}_{2} \frac{\mathrm{RT}}{\mathrm{V}}+\mathrm{n}_{3} \frac{\mathrm{RT}}{\mathrm{V}}\) |

At 300 K, 250 mL of gas A at 1 bar pressure is mixed with 500 mL of a gas B at 2 Bar pressure in a 1.0 L flask. Gas A does not react with gas B. The final pressure of the mixture is-
1. 1.00 bar
2. 2.15 bar
3. 2.50 bar
4. 1.25 bar
In water-saturated air, the mole fraction of water vapor is 0.02. If the total pressure of the saturated air is 1.2 atm, the partial pressure of dry air is-
1. 1.17 atm
2. 1.76 atm
3. 1.27 atm
4. 0.98 atm
