How many milliliter of concentrated nitric acid are required to prepare 500ml of .5 m hno3

The question is incomplete, here is the complete question:

How many milliliter of concentrated nitric acid, 16 M are required to prepare 500 mL of 0.5 M

The volume of concentrated nitric acid solution required is 15.625 mL

Explanation:

To calculate the molarity of the diluted solution, we use the equation:

where,

are the molarity and volume of the concentrated nitric acid solution

are the molarity and volume of diluted nitric acid solution

We are given:

Putting values in above equation, we get:

Hence, the volume of concentrated nitric acid solution required is 15.625 mL

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
