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 ?
Correct answer: A
Explanation
Partial pressure is found using mole fraction: P_N2 = (moles N2 / total moles) * P_total. Here, (2 / 8) * 4 kgf/cm^2 = 1 kgf/cm^2.
