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
