 * //DALTON'S GAS LAW//**

John Dalton studied the effect of gases in a mixture. He observed that the total pressure of a gas mixture was the sum of the partial pressure of each gas (P total = P1 + P2 + P3 + .......Pn ). Partial Pressure is defined as the pressure of a single gas in the mixture as if that gas alone occupied the container. In other words, Dalton said that since there was an enormous amount of space between the gas molecules within the mixture that the gas molecules did not have any influence on the motion of other gas molecules. Therefore the pressure of a gas sample would be the same whether it was the only gas in the container or if it were among other gases. Daltons law in other words is the total pressureexerted by a gaseous mixture is equal to the sum of the partial pressures of each individual component in a gas mixture.
