A 4.44 L container holds 15.4 g of oxygen at 22.55°C. What is the pressure?
We use the Ideal Gas Equation to get...........
Do the units cancel out to give an answer in
How did I do this? Well for (i) I know that oxygen is a binuclear gas, i.e.
And (ii) I knew the gas constant was...............
And (iii) I knew the relationship between
These data (well (ii) and (iii)) need not be remembered, as they should be provided (with various units) in a chemistry exam. You still need to know how to use the appropriate gas constant,
