Question

What is the molarity of a 2.00 L solution containing 4.5 moles of NaCl?

Answer 1

The molarity of a solution is given by the following formula:

`molarity=(molesofsolute)/(litersofsolution)`

Replace for the given values in the equation and find the molarity:

`molarity=(4.5mol)/(2L)=2.25M`

It means that the molarity of the solution is 2.25M.
