A230.0-ml sample of a 0.275 m solution is left on a hot plate overnight; the following morning the solution is 1.15 m. what volume of solvent has evaporated from the 0.275 m solution?

The volume of solvent evaporated is 173.57 mL

Explanation:

   .....(1)

Molarity of solution = 0.275 M

Volume of solution = 230.0 mL

Putting values in equation 1, we get:

As, the moles of solution remains the same.

When solvent gets evaporated, the volume of the solution is calculated by using equation 1:

Moles of solution = 0.0632 moles

Molarity of the solution = 1.15 M

Putting values in equation 1, we get:

Volume of solution evaporated = (230.0 - 56.43) mL = 173.57 mL

Hence, the volume of solvent evaporated is 173.57 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.
