2 Al(s) + 6 HCI(aq) → 2 AICI, (aq) + 3 H,(g)
Hydrogen gas produced by this reaction is typically collected via water displacement, during which time the hydrogen gas
becomes saturated with water vapor. A 220.0 mL sample of gas with a total pressure 149 kPa was collected via water
displacement at 29.4 °C. Calculate the partial pressure of hydrogen gas in the sample. The vapor pressure of water at
29.4 °C is 4.10 kPa.
PH, =
