please help!!

A 2.5L container has a gaseous mbxture of 32 grams of Arig) and 17 grams of O2(g). The total pressure of the gas mixture at 100.4C is 1.239104 torr. What is the partial pressure of Ar(g) in the mixture? Note that 1kPa=7.50 torr R=8.314Kmol1K1 8. 1103 tor 4.9103 tor 7.5103 tor 080 tor Question 13 The molar heat capacity at constant volume of hydrogen sulfide gas is 25.4Jmor1K1. What is the heat involved, in kJ, when 2.50 moles of H2S(g) is heated from 50.0C to 200." C at constant pressure? 12.6kJ +9.5kj +12.6kj 9.5k
