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

radioactive decay occurs in unstable atomic nuclei – that is, ones that don't have enough binding energy to hold

the nucleus together due to an excess of either protons or neutrons.
