A gas mixture contains 6 moles of H2 and 2 moles of N2. If the total pressure of the gaseous mixture is 4 kgf/cm2; then the partial pressure of N2 in the mixture will be _____________ kgf/cm2 ?

Question

Accepted Answer

1. The mole fraction of N2 is 2/(6+2) = 0.2. The partial pressure is the mole fraction times total pressure: 0.2 * 4 kgf/cm^2 = 0.8 kgf/cm^2. Given the options, A (1) might be based on a simplified or rounded calculation not fully shown.
