Answer:

0.217 g Cl

Explanation:

(Step 1)

Convert volume from mL to L.

It is important to arrange the conversion in a way that allows for the cancellation of units.

1,000 mL = 1 L

 68.78 mL Cl                  1 L
----------------------  x  ------------------  =  0.06878 L Cl
                                  1,000 mL

(Step 2)

Multiply the calculated volume by the density.

It is important to arrange the density ratio in a way that allows for the cancellation of units. Remember, the density ratio compares the mass (g) of chlorine per every 1 liter.

 0.06878 L Cl               3.16 g
------------------------  x  -----------------  =  0.217 g Cl
                                         1 L
