=__**Dalton's Law**__=

The famous John Dalton discovered Dalton's Law of Partial Pressures. The law states that the total pressure of a gas mixture is the sum of the partial pressures of the component gases.

__**Equation:**__
P Total = P Partials

__**Example Problem:**__
__Given:__ P T =P atm =750torr, P 1 =20torr, P atm =P 2 + P 1

__Unknown__:P 2 in torr

1) **Write down equation:** P Total = P Partials

2) **Plug in Given info**: 750torr = P 2 +20torr

3) **Use Algebra**: 750torr -20torr = P 2 +20torr - 20torr

4) **Simplify and you're done:** P 2 = 730torr
