What is the molar mass of a gas if \(0.0494\;{\rm{g}}\) of the gas occupies a volume of \(0.100\;{\rm{L}}\) at a temperature \({26^\circ }{\rm{C}}\)and a pressure of \({\bf{307}}\) torr?
In addition to the data found in Figure \({\rm{9}}{\rm{.13}}\), what other information do we need to find the mass of the sample of air used to determine the graph?
Determine the pressure of the gas in the syringe shown in Figure \({\rm{9}}{\rm{.13}}\) when its volume is \({\rm{12}}{\rm{.5 mL}}\), using: (a) the appropriate graph (b) Boyle鈥檚 law.
A commercial mercury vapor analyzer can detect, in air, concentrations of gaseous Hg atoms (which are poisonous) as low as 2脳10-6mg/L of air. At this concentration, what is the partial pressure of gaseous mercury if the atmospheric pressure is 733 torr at 26 虋C?
Which is denser at the same temperature and pressure, dry air or air saturated with water vapour? Explain.
