Question:
We have 0.5 g of hydrogen gas in a cubic chamber of size 3 cm kept at NTP. The gas in the chamber is compressed keeping the temperature constant till a final pressure of 100 atm. Is one justified in assuming the ideal gas law, in the final state?
Solution:
Volume of 1 molecule = 4/3 πr3 = 4.20 × 10-30 m3
No.of moles in 0.5 g H2 gas = 0.25 mole
Volume of H2 molecule in 0.25 mole = 1.04×6.023× 10+23-30
