What is the total pressure of the two gases collected over water at 24 degrees Celsius if the pressure of hydrogen gas is 3.0KPa and the pressure of water vapor is 91.4KPa

P (total) = 94.4 kpa

Explanation:

Given dа ta:

Pressure of hydrogen gas = 3.0 kpa

Pressure of water vapors = 91.4 kpa

Total pressure = ?

Solution:

According to Dalton law of partial pressure,

The total pressure exerted by mixture of gases is equal to the sum of partial pressure of the individual gas.

This expression can be written as,

P (total) = P₁ + P₂ + P₃ + ... Pₙ

Now we will put the values in formula:

P (total) = P₁ + P₂

P (total) = 3.0 kpa + 91.4 kpa

P (total) = 94.4 kpa
