Tutor description

Example of one of the problems: According to the ideal gas law, a 0.9150 mol sample of nitrogen gas in a 1.753 L container at 265.8 K should exert a pressure of 11.38 atm. By what percent does the pressure calculated using the van der Waals' equation differ from the ideal pressure? For N2 gas, a = 1.390 L2atm/mol2 and b = 3.910E-2 L/mol.

1. A prevailing pressure of one standard atmosphere will support a column of mercury 760 mm in height. Liquid carbon tetrachloride has a density of 1.59 g/mL. The height of a column of carbon tetrachloride that one standard atmosphere can support is 6500.6 mm.The density of liquid mercury is 13.6 g/mL.Density is reversely proportional to height of the barometer - aka, higher density means heavier the material means lower the height of the barometer of this material. 1. Hg - 760 mm - D=13.6 g/mL2. CCl4 - X mm - D =1.59 g/mLThe reverse proportionality is expressed as:D1xH1 = D2H2H2 (CCl4) = D1xH1 / D2D2 = 13.6 g/mL x 760 mm / 1.59 g/mLD2 = 6500.6 mmAs you see from calculations, the lighter the material - the higher up it goes. 2. Liquid methylene chloride has a density of 1.33 g/mL. A barometer is constructed using methylene chloride instead of mercury. If the atmospheric pressure is 0.952 atm, what is the height of the methylene chloride column in the barometer in cm? The density of liquid mercury is 13.6 g/mL.
