The partial pressure of hellium gas in a gaseous mixture of hellium and hydrogen is
​

Answer 1

The partial pressure of helium in a gaseous mixture with hydrogen is determined by multiplying its mole fraction by the total pressure of the mixture, according to Dalton's law of partial pressures.

Step-by-step explanation:

The partial pressure of helium gas in a mixture of helium and hydrogen can be calculated using Dalton's law of partial pressures. According to Dalton's law, the total pressure of a mixture of gases is equal to the sum of the partial pressures that each gas would exert if it were alone in the container. In a gaseous mixture containing helium and hydrogen, the partial pressure of helium (PHe) would be its mole fraction in the mixture (XHe) multiplied by the total pressure of the mixture (PTotal).

For example, if we know the mole fraction of helium and the total pressure of our mixture, we can simply multiply these two values to find the partial pressure of helium. If we had a mixture where helium contributed to a specific fraction of the total moles of gas, and we knew the total pressure in the chamber, we could use the equation PHe = XHe X PTotal to find the helium's partial pressure.

Answer 2

The partial pressure of helium gas in a gaseous mixture of helium and hydrogen is the pressure that the helium would exert in the absence of the hydrogen. equal to the total pressure divided by helium's molar mass. O equal to the total pressure divided by the number of helium atoms present.
