Answer:

the vapor pressure of mixture at 50°C is 470 mm of Hg

Explanation:

The computation of the vapor pressure is shown below:

= (420 × 1 + 480 × 5) ÷ (1 + 5)

= (420 + 2400) ÷ (6)

= 2820 ÷ 6

= 470mm of Hg

Hence, the vapor pressure of mixture at 50°C is 470 mm of Hg

The same would be considered
