Question

What is the molarity of a solution which has a volume of 3 litres and contains 5.1 moles of Br2?

Answer 1

The molarity of the solution is 1.7
`(moles)/(liter)`.

Step-by-step explanation:

Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.

The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

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

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

In this case, you know:

• moles of solute= 5.1
• volume= 3 L

Replacing:

`Molarity=(5.1 moles)/(3 L)`

Solving:

Molarity= 1.7
`(moles)/(liter)`

The molarity of the solution is 1.7
`(moles)/(liter)`.
