A student has a solution of 3.11 M MgSO4. What volume (in mL) of
the original solution is needed to make 232.0 mL of 2.44 M MgSO4?

182mL

Explanation:

Given parameters:

Molarity of solution = 3.11M

New volume  = 232mL  = 0.232dm³

New molarity = 2.44M

Unknown:

Volume of original solution  = ?

Solution:

We know the full information about the new solution we want to obtain. From this, we should find the number of moles.

Using the number of moles, we can find the original volume.

     Molarity  =

       New number of moles  = molarity x volume  = 2.44 x 0.232

                                                                                  = 0.57moles

The original volume will be;

           Volume  =   =   = 0.182dm³ or 182mL

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
