Question

Gas X makes up 15% of a gas mix, at 1000 mm Hg, the partial pressure of gas X would be

A. 11500 mm Hg
B. 1150 mm Hg
C. 1500 mm Hg
D. 150 mm Hg

Answer 1

The partial pressure of a gas within a mixture can be calculated by multiplying the total pressure by the percentage of the gas in the mixture. In this case, the partial pressure of gas X is 150 mm Hg.

Step-by-step explanation:

The question involves calculating the partial pressure of a gas within a mixture. The partial pressure of gas X, which makes up 15% of a gas mix with a total pressure of 1000 mm Hg, can be found by multiplying the total pressure by the percentage of gas X in the mix. This calculation is based on the fact that the partial pressure is proportional to the percentage of gas in the mixture:

Partial Pressure of Gas X = Total Pressure × Percentage of Gas X

= 1000 mm Hg × 0.15

= 150 mm Hg

Therefore, the correct answer is D. 150 mm Hg.
