The following reaction is used to generate hydrogen gas in the laboratory: Mg(s) + 2HCl(aq) → MgCl2(aq) + H2(g). If 243 mL of hydrogen gas is collected at 25°C and has a total pressure of 745 mm Hg, calculate the mass of hydrogen produced. Vapor pressure of water at 25°C is 23.78 mm Hg. (2 Pts.)

Question 5 (Use Data Set 1) Before every flight, the pilot must verify that the total weight of the load is less than the maximum allowable load for the aircraft. The Bombardier Dash 8 aircraft can carry 37 passengers, and a flight has fuel and baggage that allows for a total passenger load of 6200 lb. The pilot sees that the plane is full and all passengers are men. The aircraft will be overloaded if the mean weight of the...
