A 1.22 gram sample of an unknown gas is found to occupy a volume of 1.13 L at a pressure of 441 mmHg and a temperature of 45 °C. Assume ideal behavior. The molar mass of the unknown gas is __________g/mol.
Use the van der Waals equation of state to calculate the pressure of 2.00 mol of CH, at 469 K in a 5.90 L vessel. Van der Waals constants can be found in the van der Waals constants table. P = atm Use the ideal gas equation to calculate the pressure under the same conditions. P = atm Under these conditions, would you expect CH, or CCI, to deviate more from ideal behavior? Why? CCI because it occupies a smaller volume and it has greater dispersion forces between molecules. O CH, because it occupies a smaller volume and it has greater dispersion forces between molecules. CH because it occupies a smaller volume and it has smaller dispersion forces between molecules. CCI because it occupies a larger volume and it has smaller dispersion forces between molecules. O CH because it occupies a larger volume and it has smaller dispersion forces þetween molecules. O CCI, because it occupies a larger volume and it has greater dispersion forces between molecules.
