As part of another school project, you collect an unknown gas, produced during fermentation by a bacterial culture, over water. (a) If 430.0 mL of gas was collected at 33 ˚C and 0.945 atm, calculate the volume of the dry gas at 25 ˚C and 1.00 atm. (b) If the mass of the original gas sample collected was 0.568 g, estimate the molar mass of the unknown gas being produced. (Other given information: PH2O=5.03 kPa at 33 ˚C, density H2O(l)=0.996 g/mL)

Post Lab #1 A student was assigned the task of determining the molar mass of an unknown gas. The student measured the mass of a sealed 843 mL rigid flask that contained dry air. The student then flushed the flask with the unknown gas, resealed it, and measured the mass again. Both the air and the unknown gas were at 23.0°C and 750. torr. The data for the experiment are shown in the table below. Volume of sealed flask 843...
