Interpretation Introduction To determine: The vapor pressure of each component and the total vapor pressure. Explanation Given: Mass of chloroform ( m c ) is 4.08 g . Mass of acetone ( m a ) is 9.29 g . Vapor pressure of pure chloroform ( P c ∘ ) is 295 torr . Vapor pressure of pure acetone ( P a ∘ ) is 332 torr . Vapor pressure of solution ( P t ) is 312 torr . Temperature is 35 ∘ C . Molar mass of chloroform ( MM c ) is 119.38 g / mol . Molar mass of acetone ( MM a ) is 58.08 g / mol . Explanation: First, calculate the number of moles of each component as follows. The number of moles of a substance is equal to the ratio of mass to its molar mass: n = m MM Here, m is given the mass of the substance, MM is the molar mass of the substance The number of moles of chloroform ( n c ) is calculated as follows: n c = m c MM c Here, m c is the given mass of chloroform and MM c is the molar mass of chloroform. Substitute 4.08 g for m c and 119.38 g / mol for MM c : n c = 4.08 g 119.38 g / mol = 0.0341 mol So, the number of moles of chloroform is 0.0341 mol . The number of moles of acetone ( n a ) is calculated as follows: n a = m a MM a Here, m a is the given mass of acetone and MM a is the molar mass of acetone. Substitute 9.29 g for m c and 58.08 g / mol for MM c : n a = 9.29 g 58.08 g / mol = 0.1594 mol So, the number of moles of acetone is 0.1594 mol . Now, the total number of moles in the solution n is 0.1935 mol . Mole fraction of a substance is equal to the number of moles divided by total number of moles of solution. Calculate the mole fraction of chloroform ( X c ) as follows: X c = n c n Substitute 0
