The reaction of metallic aluminum with aqueous hydrochloric acid produces hydrogen gas. 2 Al(s) + 6HCl(aq) - 2 AICI, (aq) + 3H₂(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 256.7 ml. sample of gas with a total pressure 142 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, 1 137.90 Calculate the mass of aluminum that reacted to produce this quantity of hydrogen gas. mass: 0.1863 Incorrect kPa 8
