### What are the ways expressing concentration of solution?

There are a number of ways to express the relative amounts of
solute and solvent in a solution. This page describes calculations
for four different units used to express concentration:
Percent Composition (by mass)
Molarity
Molality
Mole Fraction
Percent Composition (by mass)
We can consider percent by mass (or weight percent, as it is
sometimes called) in two ways:
The parts of solute per 100 parts of solution.
The fraction of a solute in a solution multiplied by 100.
We need two pieces of information to calculate the percent by
mass of a solute in a solution:
The mass of the solute in the solution.
The mass of the solution.
Use the following equation to calculate percent by mass:

Molarity
Molarity tells us the number of moles of solute in exactly one
liter of a solution. (Note that molarity is spelled with an "r" and
is represented by a capital M.)
We need two pieces of information to calculate the molarity of a
solute in a solution:
The moles of solute present in the solution.
The volume of solution (in liters) containing the solute.
To calculate molarity we use the equation:
Top
Molality
Molality, m, tells us the number of moles of solute dissolved in
exactly one kilogram of solvent. (Note that molality is spelled
with two "l"'s and represented by a lower case m.)
We need two pieces of information to calculate the molality of a
solute in a solution:
The moles of solute present in the solution.
The mass of solvent (in kilograms) in the solution.
To calculate molality we use the equation:
Top
Mole Fraction
The mole fraction, X, of a component in a solution is the
ratio of the number of moles of that component to the total number
of moles of all components in the solution.
To calculate mole fraction, we need to know:
The number of moles of each component present in the
solution.
The mole fraction of A, XA, in a solution consisting of
A, B, C, ... is calculated using the equation:
To calculate the mole fraction of B, XB, use:

### What are the mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume-The density of water is 1.00g per mL and that of ethanol is 0.789 grams per mL?

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.
