To what volume should you dilute 51 ml of a 13 m stock hno3 solution to obtain a 0.126 m hno3 solution?

51 mL solution is diluted to to get the 0.126 M of solution.

Further explanation:

Molarity:

The molarity of the solution is defined as the concentration of the solution. It is equal to the number of moles of the solute dissolved in one liter of the solution.

The formula of molarity (M), volume (V), and number of moles (n) is as follows:

                     …… (1)

Here V is a volume of solution in liters and n is a number of moles of solute.

If n is constant and is equal to k, the equation (1) will become:

                        …... (2)

If we have initial and final values of concentration and volume then the equation (2) can be modified as follows:

             ……. (3)

Here,

is the concentration before dilution.

is the concentration after dilution.

is the volume before dilution.

is the volume after dilution.

On rearranging equation (3) for we get,

                            …… (4)

is 13 M.

is 0.126 M.

is 51 mL.

Substitute the values of , and in equation(4).

The volume of solution after dilution is 5261.90 mL.

The volume added to initial volume of solution is calculated as follows:

Hence, 51 mL is diluted to 5210.9 mL to get the 0.126 M of solution.
