1. How many grams of O2 are present at 0.5m3 and 7.5x103 Pa at 250 K? The gasconstant is 8.314x10-3 kJ/mol K, 1 J = 1 Pam3, 1000 J = 1 kJ.
2. What is the pressure in units of kPa if the gasconstant has a value of 0.08205 atm Lmol-1 K-1 and 5 grams ofCO2 (MM=44.01 g/mol) occupies a 2m3 space at 30 °C? (1 atm = 101 kPa, K = °C + 273,1 cm3 = 1 mL, 100 cm = 1 m, 1000 mL = 1 L)
3. What is the reaction enthalpy of the reaction:CS2 + 3 O2 àCO2 + 2SO2 given that the reaction enthalpy of C +O2 àCO2 is -393.5 kJ/mol, S +O2 àSO2 is -296.8 kJ/mol, and C + 2S àCS2 is +87.9 kJ/mol?
