Question

a gas mixture containing hydrogen, oxygen, and nitrogen has a total pressure of 840 torr. if p hydrogen = 320 torr and p oxygen = 485 torr, what is the partial pressure of nitrogen in the mixture? please help

Answer 1

35 torr

Step-by-step explanation:

The mixture contains 320 torr of hydrogen, 485 torr of oxygen, a total pressure of 840 torr, so you need to find the leftover

320(hydrogen) + 485(oxygen) = 805 torr

840(total) - 805 = 35 torr
