ormula is:
Molarity
=
Moles of Solute
Liters of Solution
So, the first thing I would do is convert the 750 mL to Liters. This would equal: .750 L (KHDBDCM: M->B).
Next, calculate the moles of NaCl by using the formula:
Moles
=
Amount Available
Molar Mass

So, the number of moles would be
85.0
g
of NaCl
58.44g
(
Molar Mass
)
which would equal: 1.45448323066 mol.
Next, plug the numbers into the molarity formula which would be:
1.45448323066
mol
.750
