 * Dalton's Law**

This law was named after the chemist John Dalton, after he invented it in 1801. Dalton's law of partial pressure explains that the total pressure is equal to the sum of all the pressures of the elements.

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

__Sample problem__...** 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? First start with the equation.. Ptotal= P1 + P2 Then plug in your values.. 600= 350 + P2 Then isolate P2 by subtracting 350 from both sides P2= 250mm of pressure
