Partial pressure of gas "C" = 282
The ideal gas law can, as far as we are aware, be used to represent the behavior of a single ideal gas. In a single container, various perfect gases can interact with one another in an ideal manner. Dalton's Law is an extension of the ideal gas law that functions using a partial pressure system. Each gaseous component's partial pressure measures how much pressure it would generate if it were the sole gas in the container.
According to Dalton's Law, an ideal gas mixture's total measured pressure equals the sum of its constituent partial pressures:
Total pressure of mixture (given) = 750mmhg
Partial pressure of gas "A" (given) = 125mmhg
Partial pressure of gas "B" (given) = 343mmhg
Partial pressure of gas "C" =
= 750- 125 - 343
= 282mmhg
Partial pressure of gas "C" = 282
