The gas in the reaction flask is brought to the same atmospheric pressure as the surroundings, 743.9 torr and 23.0oC. The vapor pressure of water at 23.0oC is 21.1 torr. The collected gas is found to have a volume of 652 mL. What is the partial pressure of the hydrogen gas in the collection flask? torr How many moles of hydrogen gas are contained in the collection flask? mol What mass of aluminum reacted? g (Hint: You need to determine the balanced equation for the reaction to do this problem.)
1.64 g of aluminum metal is placed in an Erlenmeyer flask with 2.50 M sulfuric acid. The hydrogen gas produced from the reaction is collected over water as shown in the diagram to the right.
The aluminum is allowed to react with the sulfuric reaction until it stops reacting, and there is still some unreacted aluminum in the reaction flask.
