Answer to Question #134534 in General Chemistry for Dog

Question

What is the partial pressure of hydrogen gas in a mixture of hydrogen and helium if the total pressure 600mm hg and partial pressure of helium is 439 mm hg?

Answer 1

P total = P hydrogen + P helium

600 mm Hg = P hydrogen + 439 mm Hg

P hydrogen = 600 mmHg - 439 mm Hg

= 161 mm Hg
