Dalton's Law-States that the total pressure of a gas mixture is the sum of the partial pressures of the component gases.

PT = Pı + P2 + P3 ... PT = the total pressure of the mixture Pı, P2 , P3 ... = partial pressures of component gases
 * Formula:**


 * Example Problem:**

P (total) = (sum) of P (partials) or the sum of all the individual pressures**
 * __Equation:__

If there is 600 mm of pressure in a container with two substances in it and hydrogen takes up 350 mm of the pressure, how much of the second substance, oxygen, will there be? Ptotal= P1 + P2

Then plug in your values

600= 350 + P2

Then isolate P2 by subtracting 350 f from both sides

P2= 250mm of pressure
