Final answer:
To find the volume of 2.00 moles of hydrogen gas at STP, multiply the number of moles by the standard molar volume, 22.4 L/mol, resulting in 44.8 liters.
Step-by-step explanation:
The volume of hydrogen gas at STP (Standard Temperature and Pressure) can be found using the standard molar volume. By definition, the standard molar volume of an ideal gas at STP, which is 0°C (273 K) and 1 atm pressure, is 22.4 liters per mole.
For 2.00 moles of hydrogen gas at STP, the calculation simply involves multiplying the number of moles by the standard molar volume:
- Volume = 2.00 moles × 22.4 L/mol
- Volume = 44.8 liters
Thus, 2.00 moles of hydrogen gas at STP occupy a volume of 44.8 liters.
