Dalton's+Law+of+Partial+Pressure

Definition – The total pressure exerted by a gaseous mixture is equal to the sum of the partial pressures of each individual component in a gas mixture.

Formula - P = P1 + P2

Example: 1.07 atm of Hydrogen is mixed with 2.05 atm of Nitrogen to make 3.12 atm of total gas

Through being a gas, the molecules are allowed to blend within a given space, as opposed to an apple and orange being mixed together, it just cannot happen.
