33 POINTS PLEASE HELP. A mixture of hydrogen and oxygen gases has a total pressure of 5.50 atm. What is the partial pressure of the hydrogen if the P (O2) = 1250 mm Hg?

2930 mmHg

Explanation:

We need to convert these two different units of pressure into the same. Let's just use mmHg. So, we need to go from atm to mmHg. The conversion factor is 1 atm = 760 mmHg. We have 5.50 atm, so multiply 760 by 5.50: 4180 mmHg.

Now, partial pressure means that the pressures of each of the different gases will add up to the total pressure. Here, our total pressure is 4180 mmHg and the pressure of oxygen is 1250 mmHg. So to find the pressure of hydrogen, we simply subtract 1250 from 4180: 4180 - 1250 = 2930 mmHg.

Hope this helps!
