molar concentration (c) = # of moles of solute (n) ÷ volume of solvent (v) in liters
So the molar mass of Nickel Chloride Hexahydrate is 237.69 g/mol.
So the # moles of 2 gms is:
[tex] \frac{1mol}{237.69g} \times \frac{2g}{1} = 8.414 \times {10}^{ - 3} moles \\ c = \frac{n}{v} = \frac{8.414 \times {10}^{ - 3} moles}{1 \: liter} \\ = 8.414 \times {10}^{ - 3}[/tex]
