This is an example of a homogenous mixture QUESTION If X and

Solution

The key equation to use is Raoult\'s Law

P_solution = P°_{x x} + P°_{y y}

b]

Partial pressure in mm of Hg due to x over the solution at 20⁰C= P°_{x x}= 40mm of Hg*0.4=16 mm of Hg

c]

P_solution = P°_{x x} + P°_{y y}

P_solution = 40mm of Hg*0.4+70mm of Hg*0.6=16 mm of Hg+42 mm of Hg= 58 mm of Hg

P_solution = 58 mm of Hg
