Question

A 225 mL sample of H2 is collected over water at 25 °C and 735 mmHg pressure. Which expression represents the set-up to find the volume of dry H2 at 0 °C and 1 atmosphere?

A.

V = (225 × (735 - 24) × 273) / (760 × 298)

✓ Correct
B.

V = (225 × 760 × 298) / ((735 - 24) × 273)

C.

V = (225 × 273 × 760) / ((735 + 24) × 298)

D.

V = (225 × (735 + 24) × 298) / (760 × 273)
