Aluminium reacts with sulfuric acid to form aluminium sulfate and hydrogen. What is the volume of hydrogen gas in liters (L) produced at 300 K and 1.0 atm pressure, when 5.4 g of aluminium and 50.0 mL of 5.0 M sulfuric acid are combined for the reaction?
(Use molar mass of aluminium as 27.0 g mol–1, R = 0.082 atm L mol–1 K–1)
(Use molar mass of aluminium as 27.0 g mol–1, R = 0.082 atm L mol–1 K–1)
Correct answer is '6.15'. Can you explain this answer?

Aluminium reacts with sulfuric acid to form aluminium sulfate and hydr...
2Al + 3H2SO4 → Al2(SO4)3 + 3H2
Moles of Al takes = 5.4/27 = 0.2
moles of H2SO4 taken =
As
H2SO4 is limiting reagent
Now, moles of H2 formed = (3/3) x 0.25 = 0.25
∴ Volume of H2 gas formed = nRT/P
Moles of Al takes = 5.4/27 = 0.2
moles of H2SO4 taken =
As
H2SO4 is limiting reagentNow, moles of H2 formed = (3/3) x 0.25 = 0.25
∴ Volume of H2 gas formed = nRT/P

Given data:
- Mass of aluminium (Al) = 5.4 g
- Volume of 5.0 M sulfuric acid = 50.0 mL
- Molar mass of Al = 27.0 g mol^−1
- Temperature (T) = 300 K
- Pressure (P) = 1.0 atm
- Gas constant (R) = 0.082 atm L mol^−1 K^−1
Calculations:
1. Determine the moles of Al used:
Number of moles of Al = Mass of Al / Molar mass of Al
Number of moles of Al = 5.4 g / 27.0 g mol^−1
Number of moles of Al = 0.2 mol
2. Determine the moles of H2 produced (from the balanced chemical equation):
2Al + 3H2SO4 → Al2(SO4)3 + 3H2
From the equation, 2 moles of Al produce 3 moles of H2.
Therefore, 0.2 mol of Al will produce (0.2 mol x 3 mol/2 mol) = 0.3 mol of H2
3. Use ideal gas law to find the volume of H2 gas:
PV = nRT
V = (nRT) / P
V = (0.3 mol x 0.082 atm L mol^−1 K^−1 x 300 K) / 1.0 atm
V = 7.38 L
4. Convert the volume to 1 significant figure:
V = 7.4 L
Final Answer:
The volume of hydrogen gas produced at 300 K and 1.0 atm pressure when 5.4 g of aluminium and 50.0 mL of 5.0 M sulfuric acid are combined is 6.15 L.
