Question

what is the molarity of a solution that contains 4.42 moles of Rubidium nitrate in 3.0 liter solution

Answer 1

The molarity of the solution is 1.473
`(moles)/(liter)`.

Step-by-step explanation:

Molar concentration is a measure of the concentration of a solute in a solution, be it some molecular, ionic or atomic species.

So, Molarity or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

Molarity is determined by:

`Molarity=(number of moles of solute)/(volume)`

Molarity is expressed in units
`(moles)/(liter)`.

In this case:

• number of moles of solute= 4.42 moles
• volume= 3 L

Replacing:

`Molarity=(4.42 moles)/(3 L)`

Molarity= 1.473
`(moles)/(liter)`

The molarity of the solution is 1.473
`(moles)/(liter)`.
