Molarity is the amount of moles of solute per volume of the solution. it can be expressed as:
`Molarity = (mol es of solute)/(Volume of the solution (L))`
Usually the unit is expressed in moles/L.
25.0 grams NaOH
First, convert the given amount of NaOH from mass to moles and obtain the molarity by dividing it with the volume of the solution.
`25.0 grams NaOH * (1 mol e NaOH)/(39.9971 grams NaOH)`
`= 0.625 mol es NaOH`
`Molarity = (0.625 mol es NaOH)/(0.750 L)`
Molarity = 0.833 Molar or M or moles/L
