What is the mole fraction of H2S in a mixture of gases made up of 7.0 g of H2S 10.0 g of CH4 and 12.0 g of O2?
First, calculate the number of moles of each gas: 7.0 g H2S = 0.25 moles, 10.0 g CH4 = 0.28 moles, and 12.0 g O2 = 0.38 moles. Next, calculate the total moles of gas in the mixture: 0.25 + 0.28 + 0.38 = 0.91 moles. Finally, calculate the mole fraction of H2S: 0.25 moles H2S / 0.91 moles total = 0.275 or 27.5%.

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.
What is the relationship between mole fraction and mass fraction in a given mixture?
The relationship between mole fraction and mass fraction in a mixture is that the mole fraction of a component is equal to its mass fraction divided by its molar mass, multiplied by the total mass of the mixture. This relationship helps in understanding the proportion of each component in the mixture based on their masses and molar masses.

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.

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.
What is the mole fraction of O2 in the mixture 02?
It is 100%.
How can one determine the mole fraction of a substance in a mixture?
To determine the mole fraction of a substance in a mixture, you divide the moles of the substance by the total moles of all substances in the mixture. This gives you a ratio that represents the proportion of that substance in the mixture.
