The molarity of the solution is **0.617 M.**

#### Explanation:

Let's use this equation:

Okay, so we have a bit of work to do! The volume is given in terms of mL and we have to convert that to L by using the following conversion factor:

Now we have to express NaCl in terms of moles. We can do this by using the molar mass of NaCl (58.44 g/mol) as a conversion factor.

Now we can divide the moles by the volume to obtain the molarity like this:

M =**0.617**
