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

Answer:
101.2%
Explanation:
Given:
Theoretical yield of the precipitate = 0.914 g
Actual yield of the precipitate = 0.925 g
Now, the percent yield is given as a ratio of actual yield by theoretical yield expressed as a percentage.
Framing in equation form, we have:
Now, plug in 0.925 g for actual yield, 0.914 g for theoretical yield and solve for % yield. This gives,
Therefore, the percent yield is 101.2%.
