Answer : The partial pressure of hydrogen gas is, 726.26 torr.
Solution : Given,
Total pressure = 753 torr
Partial pressure of water = 26.74 torr
Formula used :
Total pressure = Partial pressure of gas + Partial pressure of water
Now put all the given values in this formula, we get the partial pressure of gas.
753 torr = Partial pressure of gas + 26.74 torr
Partial pressure of the gas = 753 - 26.74 = 726.26 torr
Therefore, the partial pressure of hydrogen gas is, 726.26 torr.
