7. Gases / Partial Pressure / Problem 7

A CO2-SO2-H2O mixture was collected in a 21.0-L steel tank until the pressure reaches 861.4 torr at 58.0°C. 

(a) Calculate the moles of gas collected. 

(b) What is the partial pressure (torr) of SO2 if its concentration in the mixture is 1.83×103 parts per million (ppmv)? (Hint: ppmv = volume of component/volume of mixture) x 106.)
