what is the mole fraction, X, of solute and the molality, m (or b), for an aqueous solution that is 11.0%. Molarity: Molarity is the concentration solution which is determined by dividing the mole of the solute with the volume of solution. Here, the...
Question: What is the mole fraction and the mass percent of a solution made by dissolving 0.35 g of KBr in 0.405 L water? Mole Fraction and Mass Percent: Suppose we have a mixture with 2 components. The mole fraction of one component in the m...

Vapor pressure as a colligative property is described by Raoult’s law. Raoult’s law basically states that for an ideal solution, the vapor pressure of the total solution depends on the vapor pressure of each of the chemical components, as well as the mole fraction of each of the chemical...

Mole ratio units are either mole:mole or else it is a dimensionless number because the units cancel out. For example, it's fine to say a ratio of 3 moles of O2to 1 mole of H2is 3:1 or 3 mol O2: 1 mol H2. Mole Ratio Example: Balanced Equation ...

Mole percent (mol%) is the same as mole fraction in chemistry, but in a different guise. Multiplying the mole fraction by 100 yields the mole percentage of the given component. Mole Fraction = the number of moles of one ingredient in the given mixture the total number of moles in the ...
The mole fraction of methanol (CH₃OH) is given as 0.25. This means that in a solution, there are 0.25 moles of methanol for every 1 mole of solution. Step 2: Calculate moles of water Since the total mole fraction must equal 1, we can find the moles of water (solvent) in the so...
