- Calculate the pressure of ethanol vapor, C2H5,OH(g), at 82.0C if 1.000 mol C2H5OH(g) occupies 30.00 L. Use the van der Waals equation (see Table 5.7 for data). Compare with the result from the ideal gas law.arrow_forward99 Pure gaseous nitrogen dioxide (NO2) cannot be obtained, because NO2dimerizes, or combines with itself, to produce a mixture of NO2 and N2O4. A particular mixture of NO2, and N2O4 has a density of 2.39 g/L at 50°C and 745 torr. What is the partial pressure of NO2 in this mixture?arrow_forwardCalculate the total pressure (in atm) of a mixture of 0.0300 mol of helium, He, and 0.0400 mol of oxygen, O2, in a 4.00-L flask at 20C. Assume ideal gas behavior.arrow_forward
- A mixture of N2 and Ne contains equal moles of each gas and has a total mass of 10.0 g. What is the density of this gas mixture at 500 K and 15.00 atm? Assume ideal gas behavior.arrow_forward39 A sample containing only NO2 and SO2, has a total pressure of 120. torr. Measurements show that the partial pressure of NO2 is 43 torr. 1f the vessel has a volume of 800.0 mL and the temperature is 22.0°C, how many moles of each gas are present?arrow_forward
