The gaseous mixture has due point temperature of 15°C. The total pressure is 143.27 kPa. Determine the amount of water vapor present in 100-moles of the mixture. Note: Saturation pressure is at 15°C is 1.7051 kPa.

A volume of 400 cc of air is measured at a pressure of 740 mm Hg abs and a temperature of 18°C. what will be the volume at 760 mm Hg abs and 0°C?  

If 8 kg of air at 27°C are heated at constant pressure until the absolute temperature doubles, calculate the heat required in kJ.    

An air bubble rises from the bottom of a well where the temperature is 25°C to the surface where the temperature is 27°C. Find the percent increase in the volume of the bubble if the depth of the well is 5 m. Atmospheric pressure is 101,528 Pascals.

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
