A 500. mL sample of oxygen is collected over 20.0∘C water at 760. torr. If the vapor pressure of water at 20∘C is 23.8 torr, what is the vapor pressure of the dry oxygen gas?
Added by Heather S.
Step 1
We can use Dalton's law of partial pressures, which states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each individual gas. The total pressure of the collected sample is 760 torr, and the vapor pressure of water Show more…

A sample of oxygen gas, which is saturated with water vapor, is kept in a 10-L vessel at 30 oC and has a pressure of 758 Torr. If the pressure of the water vapor at this temperature is 31.8 Torr, what would be the pressure of the dry oxygen?

A 2.00 -L sample of $\mathrm{O}_{2}(g)$ was collected over water at a total pressure of 785 torr and $25^{\circ} \mathrm{C}$ . When the $\mathrm{O}_{2}(g)$ was dried (water vapor removed), the gas had a volume of 1.94 $\mathrm{L}$ at $25^{\circ} \mathrm{C}$ and 785 torr. Calculate the vapor pressure of water at $25^{\circ} \mathrm{C}.$
