If you wanted to make 0.800 Liters of a 0.531 M solution of Nickel(II) chloride, NiCl2, how many grams of NiCIZ
would you need? Use the unit canceling method to determine the grams of NiCl2
Molar mass= 129g/mol. Moles = 0.4248
.

Explanation:

1. Calculate the number of moles of NiCl₂

a) Identify the known variables

b) Formula

c) Clear n

g) Substitute and compute

2. Convert moles to grams

a) molar mass of NiCl₂

b) Unit canceling method

Use the factors in order to cancel the units to obtain grams

Note that the mol unit appears on the numerator and denominator, so it cancels leaving just g (grams).

c) Round to 3 signficant figures
