Answer:
Explanation:
After the first hour, 20% of the liquid evaporates, which leaves 80% of the liquid remaining in the beaker.
The amount of liquid remaining after the first hour is:
50 mL x 0.8 = 40 mL
After the second hour, another 20% of the remaining liquid evaporates, which leaves 80% of the remaining 40 mL: 40 mL x 0.8 = 32 mL
We can repeat this process for each of the remaining 4 hours:32 mL x 0.8 = 25.6 mL
25.6 mL x 0.8 = 20.48 mL
20.48 mL x 0.8 = 16.384 mL
16.384 mL x 0.8 = 13.1072 mL
Therefore, after 6 hours, approximately 13.1072 mL of liquid would be left in the container.
