Question

A 5.2 L closed container contains some water and N$_2$(g) at 29 $^\circ$C. The total pressure of the system and water tension are 1 atm and 0.04 atm, respectively. Upon electrolysing the liquid water inside completely, the final pressure of system was at 2 atm. What is number of moles of water that was present inside the container?

• A. $\frac{3.46}{RT}$
• B. $\frac{5.2}{RT}$
• C. $\frac{10.4}{RT}$
• D. $\frac{0.208}{RT}$
• E. $\frac{8.0}{RT}$

Hint:

Aqueous tension is the pressure exerted by water vapor in equilibrium with liquid water; it is a partial pressure.

Answer 1

The Correct Option is D
