A steel tank contains a mixture of Ar and He gases. If the partial pressure of helium in the tank is 1085 mmHg, and the partial pressure of argon is 4867 mmHg, what is the total pressure in the tank (in atm)? Answer as a whole number

Answer:

8 atm

Explanation:

Given data:

Partial pressure of Ar = 4867 mmHg

Partial pressure of He = 1085 mmHg

Total pressure = ?

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(Ar) + P(He)

P(total) =  4867 mmHg +  1085 mmHg

P(total) =  5952 mmHg

mmHg to atm;

5952 /760 = 7.83 atm

P(total) = 8 atm
