If you wanted to make 0.800 Liters of a 0.531 M solution of Nickel(II) chloride, NiCl2, how many grams of NiCIZ
kotegsom [21]

Answer:

<u></u>

  • <u>54.8g</u>

Explanation:

<u>1. Calculate the number of moles of NiCl₂</u>

a) Identify the known variables

  • V =0.800 liters
  • M = 0.531M
  • n = ?

b) Formula

       M=\dfrac{n}{V}

c) Clear n

        n=M\times V

<u>g) Substitute and compute</u>

         n=0.531M/times 0.800liters=0.4248mol

<u>2. Convert moles to grams</u>

a) molar mass of NiCl₂

  • 129g/mol (shown in the problem)

b) Unit canceling method

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

      0.4248mol\times 129\dfrac{g}{mol}=54.7992g

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

c) Round to 3 signficant figures

     54.8g
