A mixture of gas has a total pressure of 105 mmHg. If the mixture is 68% neon what is the partial pressure of the neon?

From ideal gas formula PV=nRT, we can conclude that the pressure is influenced by the number of moles of the gas. When the gas is mixed, partial pressure of a gas is determined by the total pressure and percentage of mol of the gas. A gas with higher percentage will result in higher partial pressure.

So, the partial pressure of the neon would be: 105 mmHg * 68% = 71.4mmHg
