Concept explainers
Interpretation:
Partial pressure of H2 has to be determined using the given data.
Concept Introduction:
Dalton’s law of partial pressure:
According to this law, the total pressure exerted by each gas in a mixture is equal to the sum of the individual partial pressure of the gases.
Partial pressure: It is the pressure of each gas in a mixture of gases.
Mole fraction: Quantity which defines the number of moles of a substance in a mixture divided by the total number of moles of all substances present.
Xa = nantotal
Partial pressure of a gas in the mixture of gases is the product of mole fraction of the gas and the total pressure.
Pa = Xa × Ptotal

What mole fraction of NaCl is needed to raise the boiling point of H2O by 3˚C? Does the amount of salt added to water (typically about one teaspoon to four quarts of water) substantially change the boiling point? (Kb (H2O) = 0.51˚C/molal.)arrow_forward
