Please answer these questions on your Page 11
In a 20.0 L steel container, we have only 77.7 g of CO₂(g), 77.7 g of N₂(g), and O₂(g).
The temperature is 25.0°C and the total pressure is 8.88 atm. What mass of O₂(g) do we have, and
what is its partial pressure? The molar masses of C, N, and O are 12.01, 14.01, and 16.00 g/mol.
(b)
The density of a sample of pure CH₂(g) at a constant pressure of 2.22 atm is 0.444 g/L.
What is the average speed, or root mean square speed, of the CH₁ (g) molecules in this sample? The
molar masses of C and H are 12.01 and 1.01 g/mol.
