Ответ:
760 mmhg - 526 mmhg = 234 mmhg
since only water is present in the jar and helium is not soluble in water, the partial pressure of water can also be taken as the saturation pressure. using the steam table, we can determine the temperature of the water based on the saturation pressure. and the temperature is 68°c.
