A metal tank contains three gases: oxygen, helium, and nitrogen. If the partial pressures of the three gases in the tank are 5.75 atm of O2, 7 atm of N2, and 2.25 atm of He, what is the total pressure inside of the tank

P(total) = 15 atm

Explanation:

Given data:

Pressure of O₂ = 5.75 atm

Pressure of N₂ = 7 atm

Pressure of He = 2.25 atm

Total pressure inside tank = ?

Solution:

According to Dalton law of partial pressure,

The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.

Mathematical expression:

P(total) = P₁ + P₂ + P₃+ +Pₙ

Now we will solve this  problem by using this law.

P(total) = P(O₂) + P(N₂) + P(He)

P(total) = 5.75 atm + 7 atm + 2.25 atm

P(total) = 15 atm

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.
