There is only one mole of NaOH will be needed to make 1M solution.
Any mixture with one or more solutes that have been dissolving in a solvent is usually referred to as a solution. To create a homogenous mixture, a solute must dissolve in a solvent. To create a homogenous mixture, a solute must dissolve in a solvent.
The SI standard unit of the material amount would be the mole, denoted by the sign mol. How several elementary entities of a specific substance are present in an object or sample is determined by its quantity.
Molarity is calculated by dividing the number of moles of the solution example, sodium hydroxide, or NaOH by the number of liters of solution. Simply put, 1 mole of solute will be dissolved into one liter of solution in such a 1-M solution.
By the definition of there is only one mole of NaOH will be needed to make 1M solution.
