Does the mole of solution is equal to mole of solute plus mole of solution?
No, the mole of solution is not equal to the mole of solute plus the mole of solvent. The mole of solution refers to the total amount of moles in a given volume of solution, which includes both the solute and the solvent.
What is the mole fraction of solute in 3.52m aqueous solution?
To find the mole fraction of solute in a 3.52 m (molal) aqueous solution, we first need to determine the moles of solute and the moles of solvent (water). A 3.52 m solution means there are 3.52 moles of solute per 1 kg of water. The molar mass of water is approximately 18.015 g/mol, which corresponds to about 55.5 moles of water in 1 kg. The mole fraction of solute (X_solute) can be calculated using the formula: [X_{\text{solute}} = \frac{\text{moles of solute}}{\text{moles of solute} + \text{moles of solvent}} = \frac{3.52}{3.52 + 55.5} \approx 0.059. ] Thus, the mole fraction of solute is approximately 0.059.
What is the mole fraction of solute in a 3.85 m aqueous solution?
To find the mole fraction of the solute in a 3.85 m (molal) aqueous solution, we first need to determine the number of moles of solute and the mass of the solvent (water). In a 3.85 m solution, there are 3.85 moles of solute per kilogram of water. Assuming 1 kg of water as the solvent, the total moles of the solution will be 3.85 moles of solute plus 55.5 moles of water (since 1 kg of water is approximately 55.5 moles). The mole fraction of the solute is then calculated as the number of moles of solute divided by the total moles: ( \text{Mole fraction} = \frac{3.85}{3.85 + 55.5} \approx 0.065 ).
Why doesn't adding one mole of solute to one liter of water make a one molarity solution?
molarity of moles of solute/liters of solution(not solvent) the volume of the solvent(even if it started at 1 L) would change after adding the solute depending on the molar mass, density, etc of the solute, the molarity would be different
Why does vapor pressure of a saline-solution lower than a pure solvent?
The vapor pressure of a saline solution is lower than that of a pure solvent due to the presence of solute particles, which in this case are the salt ions. When salt dissolves in water, it dissociates into ions, reducing the number of solvent molecules at the surface that can escape into the vapor phase. This phenomenon is explained by Raoult's Law, which states that the vapor pressure of a solution is directly proportional to the mole fraction of the solvent, leading to a decrease in vapor pressure as solute concentration increases. Consequently, the presence of solute particles hinders the evaporation of solvent molecules, resulting in lower vapor pressure.
Does the mole of solution is equal to mole of solute plus mole of solution?
No, the mole of solution is not equal to the mole of solute plus the mole of solvent. The mole of solution refers to the total amount of moles in a given volume of solution, which includes both the solute and the solvent.
What is the mole fraction of solute in a 3.82 m aqueous solution?
To find the mole fraction of solute, you need to know the moles of solute and solvent. In this case, the moles of solute can be calculated by multiplying the molarity of the solution by the volume of the solution. Once you have the moles of solute and solvent, you can find the mole fraction of solute by dividing the moles of solute by the total moles of solute and solvent.
What is the mole fraction of solute in a 3.62 m aqueous solution?
To find the mole fraction of solute in a solution, you need to know the total moles of both the solute and the solvent. In this case, the moles of the solute is 3.62 mol and the moles of the solvent (water) is not given. Without the moles of the solvent, the mole fraction of the solute cannot be calculated.
What is the mole fraction of solute in a 3.30 m aqueous solution?
To find the mole fraction of solute, we need to know the moles of solute and moles of solvent. Here, the concentration (3.30 m) tells us the moles of solute per liter of solution, but we need more information to calculate the mole fraction. We would need the moles of solute and moles of solvent to proceed.
What is the mole fraction of solute in a 3.71 m aqueous solution?
molal = m = moles solute/kg solvent. Assuming water as the solvent 1 kg = 1000 g/18g/mole = 55.56 moles H2O. Moles solute = 3.71 moles. Total moles present = 55.56 + 3.71 = 59.27 moles.Mole fraction solute = 3.71/59.27 = 0.0626
What is the mole fraction of solute in a 3.72 m aqueous solution?
To find the mole fraction of solute in a solution, you need both the moles of solute and the total moles of solute and solvent combined. In this case, the molarity of the solution (3.72 mol/L) is not enough information to determine the mole fraction without knowing the specific solute and its moles.
How can the molality of a solution be converted to its corresponding mole fraction?
To convert the molality of a solution to its corresponding mole fraction, you can use the formula: Mole fraction (molality / (molality 1000)) This formula calculates the ratio of the moles of solute to the total moles of solute and solvent in the solution.

To find the mole fraction of solute, we need to first determine the moles of solute and solvent. In a 3.12 molal solution, there are 3.12 moles of solute in 1 kg of solvent. Using the density of water (1 g/mL), we can convert the 1 kg of solvent to 1000 g. Knowing the molar mass of water (18 g/mol), we can convert 1000 g to moles. Finally, the mole fraction of solute is the moles of solute divided by the total moles of solute and solvent.

To determine the mole fraction from vapor pressure, you can use Raoult's Law.
