The mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume and the density of water is 1.00g per mL that of ethanol is 0.789 grams per mL and 70/18. A mole fraction in chemistry is the amount that is divided by the total amount of all constituents.

Calculate the mole fraction of HCl in 20 percent aqueous solution?
The mole fraction of HCl in a 20% aqueous solution can be calculated by converting the percentage to a molarity concentration. Assuming the density of the solution is 1 g/mL, a 20% solution means 20g of HCl in 100g of solution. If the molar mass of HCl is 36.5 g/mol, we can calculate the molarity and then use it to find the mole fraction of HCl in the solution.
Water is a solvent in a(n) what solution?

What concentration of aqueous CaCl2 solution freezes at -10.2ºC The freezing point of pure water is 0.0ºC and Kf of pure water is -1.86ºC m?
To calculate the molality of the solution, we first need to determine the change in freezing point. ΔTf = 0.0°C - (-10.2°C) = 10.2°C. Next, use the formula ΔTf = Kf * m to find molality. Rearrange the formula to solve for molality: m = ΔTf / Kf = 10.2°C / 1.86°C m^-1 = 5.48 m. Thus, the concentration of the solution is 5.48 mol/kg.

What is the boiling point of an aqueous solution that has a vapor pressure of 18.5 at 25 degrees Celsius?
The boiling point of an aqueous solution can be calculated using the formula: ΔT = iKbm, where ΔT is the boiling point elevation, i is the van't Hoff factor, Kb is the ebullioscopic constant, and m is the molality of the solution. Given the vapor pressure of 18.5 mmHg, you can determine the molality of the solution and then calculate the boiling point elevation.

Is the boiling point of a 0.5 m aqueous solution of KOH higher than the boiling point of a .5m aqueous solution of KCL?
Colligative properties, such as boiling point elevation, depend on the molality of the solution and the number of "entities" (ions, in this case) per formula unit. For the solutions specified, these are identical, so the answer is no.

Aqueous solutions are solutions in which water is the solvent. Anything that dissolves in water forms an aqueous solution.
Is a aqueous solution a solution that contains all the solute that it can hold?
the solution itself, yes. it must contain water to be called an aqueous solution. the term aqueous designates water as the solvent/diluent.
How do you use the word aqueous in a sentence?

How is an aqueous solution different from other solutions?
In an aqueous solution the solvent is water.
What is aqueous solvent?
The aqueous solvent is water in a solution. An aqueous solution is a mixture that consists of the solvent water and a substance called a solute. For example, by dissolving the solute sugar in water, you get an aqueous solution.
