Question

The total pressure in a flask containing only hydrogen and helium is 580 mmHg. If hydrogen accounts for 70% of the pressure and helium contributes 30% of the pressure, what is the partial pressure of the hydrogen gas?

A) 406 mmHg
B) 510 mmHg
C) 174 mmHg
D) 83 mmHg

Answer 1

Answer choice c = 174

Step-by-step explanation:

If you divide 30% into 580 you get 174. You can also check your work by doing 580 divided by 70%

30% divided by 580 = 174
