Question

In a mixture of He, Ne, and Kr the total pressure is 125 kPa. The partial

pressure of Ne is 31 kPa, and the partial pressure of Kr is 21 kPa. What is
the partial pressure of He?

Answer=______?

Answer 1

Partial pressure of He = 73 kPa

Step-by-step 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
