Partial pressures of SO2 and N23.00 g of SO2(g) is originally in a 5.00 L vessel at 21 degrees Celsius and is transferred to a 10.0 L vessel at 26 degrees Celsius. 2.35 g N2(g) is originally in a 2.50 L vessel at 20 degrees Celsius and is transferred to the same 10.0 L vessel.
- what is the partial pressure of SO2(g) in the larger container?- what is the partial pressure of N2(g) in this vessel- what is the total pressure of the vessel?
