Answer:
0.217 g Cl
Step-by-step 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
