1. An 11.2-L sample of gas is determined to contain 0.50 mole of N2. At the same temperature and pressure, how many moles of gas would there be in a 20.-L sample?
2. Consider the following chemical equation.
2NO2 (g) N2O2 (g)
If 25.0 mL NO2 gas is completely converted to N2O4 gas under the same conditions, what volume will the N2O2 occupy?
3. Complete the following table for an ideal gas.
