Question

A rigid container contains a mixture of 3 gases. The pressure of the gases are gas A is 445 mmHg, Gas

Bis 560 mmHg, and Gas C is 622 mmHg. What is the total pressure in the container?

Answer 1

`P_T = 1627\text{ mm Hg}`

Step-by-step explanation:

Dalton's law of partial pressures states that the total pressure in a mixture of gases is the sum of the partial pressures of the individual gases.

In other word:

`\displaystyle P_T = P_A + P_B + P_C`

Therefore, the total pressure of the mixture of three gases is:

`\displaystyle \begin{aligned} P_T & = (445 \text{ mm Hg}) + (560\text{ mm Hg}) + (622\text{ mm Hg}) \\ \\ & = 1627 \text{ mm Hg}\end{aligned}`

In conclusion, the total pressure of the mixture is 1627 mm Hg.
