Question

A flask contains argon, helium, and fluorine gases. The partial pressures of each are 14.1 Torr, 12.2 Torr, and 8.6 Torr, respectively. What is the total pressure in the flask of Torr?

Answer 1

Answer : The total pressure in the flask is, 34.9 torr

Explanation :

As we know that the total pressure is the sum of the partial pressure of the gases.

The formula used is :

`p_T=p_(Ar)+p_(He)+p_(F)`

where,

`p_T` = total pressure in the flask = ?

`p_(Ar)` = partial pressure of argon = 14.1 torr

`p_(He)` = partial pressure of helium = 12.2 torr

`p_(F)` = partial pressure of fluorine = 8.6 torr

Now put all the given values in the above formula, we get

`p_T=14.1+12.2+8.6=34.9torr`

Therefore, the total pressure in the flask is, 34.9 torr
