A 100 gallon man-made fish pond is to have a consistent 1.06% by weight of copper sulfate solution to be able to maintain an algae-free environment otherwise all the fish will die. If the copper sulfate in the pond decomposes at the rate of 125 g/day, 350 g/week is adsorbed by the fish through their scales and 357.5 g/day is consumed to kill the algae spores. Assuming that evaporation is negligible and the water is kept constant with regards to volume, how much copper sulfate (in grams) is needed to be added initially in the pond and every week thereafter considering that the initial percentage of the pond is only 0.5%?

Question
Transcribed Image Text:A 100 gallon man-made fish pond is to have a consistent 1.06% by weight of copper
sulfate solution to be able to maintain an algae-free environment otherwise all the fish
will die. If the copper sulfate in the pond decomposes at the rate of 125 g/day, 350
g/week is adsorbed by the fish through their scales and 357.5 g/day is consumed to kill
the algae spores. Assuming that evaporation is negligible and the water is kept constant
with regards to volume, how much copper sulfate (in grams) is needed to be added
initially in the pond and every week thereafter considering that the initial percentage of
the pond is only 0.5%?
