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 mixture is obta...
The mole fraction of a compound in a solution describes the moles of the particular compound over the total moles of all of the components in the solution. For the mole fraction of water in the KCl solution, it is equal to the moles of water over the sum of the moles of wate...

Molar 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. Molar Ratio Example: Balanced Equation ...
