Question
What pressure of H, gas is produced if 42.28 g of Al is reacted with excess HCl in a sealed 15.1 L container at a temperature of
279 K?
4 Al(s) + 7 HC1(aq) → 4 AICI, (aq) + 6 H, (g)
First, calculate the number of moles of H, formed in this reaction and show the conversions required to solve this problem.
42.28 g Al ×
mol H2
Answer Bank
1 mol HCI
6 mol HCI
26.98 g Al
1 mol Al
2.02 g H,
2 mol Al
2 mol AICI,
1 mol AICI,
133.34 g AICI,
36.46 g HCI
1 mol H,
3 mol H,
Then, use the ideal gas law to calculate the pressure of H, gas.
P =
atm
