The health of fish depends on the amount of oxygen dissolved in the water. A dissolved oxygen (DO) concentration between 6 parts per million and 8 parts per million is best for fish health. A DO concentration greater than 1 part per million is necessary for fish survival. A student’s fish tank contains fish, green plants, and 3800 grams of fish-tank water with 2.7 × 10 -2 gram of dissolved oxygen. Write a statement using this information that tells why the DO concentration in the water is or is not healthy for fish.
