Final answer:
The corrected volume of hydrogen gas at STP is calculated using the combined gas law and is found to be 22.4 L, as the molar volume of any gas at STP is 22.4 L per mole.
Step-by-step explanation:
The subject of this question is Chemistry, specifically the application of the combined gas law and concept of molar volume to calculate the volume of a gas at standard temperature and pressure (STP).
Applying the combined gas law (P1 x V1 x T2) / (P2 x T1) = V2, we can solve for V2 given the values:
- P1 = 722.2 mm Hg
- V1 = 2.58 L
- T1 = 293 K (which is the initial temperature)
- P2 = 760 mm Hg (which is the pressure at STP)
- T2 = 273 K (which is the temperature at STP)
Performing the calculation, we get:
(722.2 mm Hg x 2.58 L x 273 K) / (760 mm Hg x 293 K) = V2
After the units cancel out, we find that V2 = 22.4 L, confirming that at STP, the molar volume of any gas is 22.4 L per mole. Hence, the "corrected" volume of hydrogen at STP is 22.4 L.
