First calculate the moles of each gas using their molar masses (H2S = 34 g/mol, CH4 = 16 g/mol, O2 = 32 g/mol). Then find the total moles in the mixture. Lastly, divide the moles of H2S by the total moles to get the mole fraction of H2S in the mixture.

Why mole fraction of gases is always equal to unity?
The mole fraction of gases is not always equal to unity. The mole fraction of a gas in a mixture is equal to the number of moles of that gas divided by the total number of moles of all gases in the mixture. It is a dimensionless quantity that ranges from 0 to 1.
What is the partial pressure of gas in a mixture of gases?
The partial pressure is the pressure exerted by just one gas in the mixture.
The partial pressure of F2 in a mixture of gases where the total pressure is 1atm is 300 torr what is the mole fraction of F2?
The mole fraction of F2 can be calculated using the equation: Mole fraction of F2 = Partial pressure of F2 / Total pressure of the mixture Mole fraction of F2 = 300 torr / 760 torr = 0.3947
What is the partial of a gas in a mixture of gases?
The partial pressure is the pressure exerted by just one gas in the mixture.
What is the mole fraction of oxygen in a gas mixture that is 37 percent oxygen and 63 percent nitrogen in volume?
To find the mole fraction of oxygen, first convert the percentages to fractions: 37% oxygen is 0.37 and 63% nitrogen is 0.63. Since the total mole fraction in a mixture is 1, the mole fraction of oxygen would be 0.37/(0.37 + 0.63) = 0.37/1 = 0.37. Therefore, the mole fraction of oxygen in the gas mixture is 0.37.

State relation between mole fraction and Volume fraction?
For Ideal gases, mole fraction=volume fraction
When can volume fraction be equal to mole fraction?
The volume fraction of a substance is equal to the mole fraction for ideal gas mixture
A mixture of gases contains 0.25 mol oxygen gas and 1.50 mol carbon dioxide gas at STP the mole fraction of oxygen gas in its mixture is?
The total moles of gas in the mixture is 0.25 + 1.50 = 1.75 mol. The mole fraction of oxygen gas is the moles of oxygen gas divided by the total moles, so 0.25 mol / 1.75 mol = 0.143. Therefore, the mole fraction of oxygen gas in the mixture is 0.143.
The partial pressure of F2 in a mixture of gases where the total pressure is 1atm is 300 torr what is the mole fraction of F2?
The mole fraction of F2 can be calculated using the equation: Mole fraction of F2 = Partial pressure of F2 / Total pressure of the mixture Mole fraction of F2 = 300 torr / 760 torr = 0.3947

Since the total mole fraction in a mixture is 1, the mole fraction of oxygen would be 0.37/(0.37 + 0.63) = 0.37/1 = 0.37. Therefore, the mole fraction of oxygen in the gas mixture is 0.37.
What is the mole fraction of O2 in the mixture 02?
It is 100%.
A mixture of gases contains 0.25 mol oxygen gas 0.75 mol nitrogen gas and 1.50 mol carbon dioxide gas at STP The mole fraction of carbon dioxide gas in this mixture is?
The total moles of gas in the mixture is 0.25 + 0.75 + 1.5 = 2.5 mol. The mole fraction of carbon dioxide gas is the moles of CO2 divided by the total moles of gas, which is 1.5 mol / 2.5 mol = 0.6. So, the mole fraction of carbon dioxide gas in the mixture is 0.6.
What is the unit of mole fraction?
Mole fraction is dimensionless. It's the amount of moles of species "A" divided by the total amount of moles in the mixture. So "mole A / mole total" equals "dimensionless". To add clarity in the use of mole fractions, one could add as "unit" mole A / mole "mixture".
