Question

Trimix 10/50 is a gas mixture that contains 10% oxygen and 50% helium, and the rest is nitrogen. If a tank of Trimix 10/50 has a total pressure of 2.07 × 10^4 kPa, then what is the partial pressure of helium?

Answer 1

Answer:

1.04x10^4 kpa

Explanation:

Answer 2

The partial pressure of helium in the gas mixture is 1.035×10⁴ KPa

Data obtained from the question

• Oxygen = 10%
• Helium = 50%
• Nitrogen = 100 – (10 + 50) = 40%
• Total pressure = 2.07×10⁴ KPa
• Partial pressure of helium =?

How to determine the partial pressure of helium

The partial pressure of helium can be obtained as follow:

• Helium = 50%
• Total pressure = 2.07×10⁴ KPa
• Total percentage = 100%
• Partial pressure of helium =?

Partial pressure of helium = (percent of helium / total percent) × total pressure

Partial pressure of helium = (50 / 100) × 2.07×10⁴

Partial pressure of helium = 1.035×10⁴ KPa
