The total pressure inside a vessel containing a mixture of neon, argon, and helium gases is 750 kpa. the partial pressure of neon is 230 kpa, and the partial pressure of argon is 250 kpa. what is the partial pressure of helium?

Answer :  The partial pressure of is, 270 Kpa

Solution :

According to the Dalton's law, the total pressure of the gas is equal to the sum of the partial pressure of the mixture of gasses.

where,

= total partial pressure = 750 Kpa

= partial pressure of helium = ?

= partial pressure of neon = 230 Kpa

= partial pressure of argon = 250 Kpa

Now put all the given values is expression, we get the partial pressure of the helium gas.

Therefore, the partial pressure of is, 270 Kpa

answer : a model is often used to explain and make things easier to understand when any scientific topic needs to be demonstrated and explained.

as in this case where a scientist wants to use a model to present the results of his detailed scientific investigation. he should do it as it will him to make the audience understand the concept in a much better way. also, it can be changed according to new scientific understandings.
