Question

a naoh (aq) stock solution was created by dissolving 3.88 g naoh in water to create a 100.00 ml solution. what is the concentration of this solution? [ select ] m perform a ten fold dilution to create three more solutions. what are the concentrations of these solutions? dilution

Answer 1

3.88 g of naoh were dissolved in water to make a 100.00 ml stock solution of naoh (aq). As a result, the mass of NaOH in grams is 12.5g, and the concentration of this solution is 4.85 mol/L.

What is a solution's Concentration?

The quantity of solute that has been dissolved in a certain volume of solvent or solution is measured by the solution's concentration. A solution that contains a significant amount of dissolved solute is said to be concentrated. A solution is said to be dilute if it only contains a little quantity of dissolved solute.

Mass of a constituent (solute) divided by the volume of the solution in milliliters can be used to describe a solution's concentration.

Mathematically:

C = mass of solute / volume of solution

In this case,

mass of solute (NaOH)= 3.88g

Concentration of Solution = 0.125M

Volume of solution =100mL

According to the formula of concentration...

c = 3.88 / 100

0.125 = 3.88 / 100

         = 4.85 mol/L
