Homework Statement



(introduction course of university physics)

A 25- L container holds ideal hydrogen (H2) gas at a gauge pressure of 0.25 atm and a

temperature of 0°C. What mass of hydrogen gas is in this container? The ATOMIC mass of

hydrogen is 1.0 g/mol, the ideal gas constant is R = 8.314 J/mol•K = 0.0821 L ∙ atm/mol ∙ K, and

1.00 atm = 101 kPa.

A) 1.4 g B) 6.3 g C) 4.2 g D) 2.8 g E) 5.6 g

Answer:D

Homework Equations
