How many milliliters of a 0.266 m kno3 solution are required to make 150.0 ml of 0.075 m kno3 solution?

The volume of required to make the unknown solution is 42.30 mL.

Explanation:

To calculate the volume required to make the given molar solution, we use the equation:

where,

are the molarity and volume of initial solution respectively

are the molarity and volume of final solution respectively.

We are given:

Putting values in above equation, we get:

Hence, the volume of required to make the unknown solution is 42.30 mL.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
