How to do this partial pressure question?
The question states:
A gas mixture consists of 60.0% Ar, 30.0% Ne, and 10.0% Kr by volume. If the pressure of this gas mixture is 80.0 kPa, what is the partial pressure for each of the gases?
No clue how to solve this, halp

Use Dalton's Law of Partial Pressures. Which says that all the partial pressures will add up to the total pressure.
Explanation:
The total pressure is 80.0 kPa.
So 60% of that 80.0 kPa is Argon.
and 30% of that 80.0 kPa is Neon, and so on.
60 % = 60/100 = .6
so (.6)(80.0 kPa) = 64 kPa so 48 kPa is Argon.
and (.3)(80.0 kPa) = 24 kPa so 24 kPa is Neon.
and so on..
