An ideal gas at 45 psig and 80°F is heated in a closed container to 130°F. What is the final pressure?   

. A one cubic meter tank contains a mixture of 2.5 kg of nitrogen and 4.5 kg of the unknown gas. The mixture pressure and temperature are 350 kPa and 80°c respectively. The gas constant for nitrogen is 0.2968 kJ*/kg- °K. Determine the gas constant of the unknown gas in kJ/kg-°K.   

2 C₂H_6(g) +7 O_2(g) = 4 CO_2(g) + 6 H₂O_(g)

1. Calculate the volume in liters of CO₂ at STP, that could be produced from 7.25 g C₂H₆.

2. Calculate the volume of O₂ at 100^oC and 1.25 atm, that would react with 7.52g of C₂H₆
