Final answer:
To find out how much lead can be obtained from 34.0 quarts of water, we multiply the volume of water in milliliters by the concentration of lead. The amount of lead obtained is approximately 1,449,428.59 micrograms.
Step-by-step explanation:
To find out how much lead can be obtained from 34.0 quarts of water, we need to convert quarts to milliliters and then use the given concentration of lead in the lake.
1 quart is equal to 946.353 milliliters, so 34.0 quarts of water is equal to 34.0 x 946.353 = 32,209.502 milliliters.
To find the amount of lead, we can multiply the volume of water in milliliters by the concentration of lead in micrograms per milliliter:
32,209.502 milliliters x 45.0 micrograms/milliliter = 1,449,428.59 micrograms of lead
