Let calculate the mole fraction nitrogen the mixture hgnext

To determine the mass of hydrogen (H₂) present in the gas mixture, we need to use the given information about the partial pressure of nitrogen and the total pressure of the mixture. We can utilize the concept of partial pressure and Dalton's law of partial pressures.

Dalton's law of partial pressures states that the total pressure of a mixture of gases is equal to the sum of the partial pressures of each component gas.

First, let's calculate the mole fraction of nitrogen (X_nitrogen) in the mixture:

X_nitrogen = P_nitrogen / P_total

P_hydrogen = P_total - P_nitrogen

Now, let's substitute the given values into the equation to find the partial pressure of hydrogen:

moles of nitrogen = mass of nitrogen / molar mass of nitrogen

The molar mass of nitrogen (N₂) is 28.0134 g/mol.

Now that we have the moles of hydrogen, we can find its mass by multiplying it by the molar mass of hydrogen (2.01588 g/mol).

Please note that the molar mass of hydrogen (H₂) is 2.01588 g/mol.
