Answer:
Partial pressure of He = 73 kPa
Explanation:
Given:
Total pressure = 125 kPa
Partial pressure of Ne = 31 kPa
Partial pressure of Kr = 21 kPa
Find:
Partial pressure of He
Computation:
Total pressure = Partial pressure of Ne + Partial pressure of Kr + Partial pressure of He
125 kPa = 31 kPa + 21 kPa + Partial pressure of He
Partial pressure of He = 73 kPa
