Partial pressure of Ne = 366 mmHg

Explanation:

In a mixture, the sum of partial pressures for each gas, is the total pressure for the system.

Partial pressure He: 43 mmHg

Partial pressure Ar: 835 mmHg

Partial pressure Xe: 111 mmHg

Partial pressure Ne:?

Total pressure = 1355 mmHg

43 + 835 + 111 + x = 1355

989 + x = 1355

x = 1355 - 989 → 366
