Final answer:
The science experiment, which uses 2 milligrams of a chemical compound, can be repeated 75,000 times with 1.5 hectograms of the compound available.
Step-by-step explanation:
The question asks how many times a science experiment can be repeated if the experiment uses 2 milligrams of a certain chemical compound, while the lab has 1.5 hectograms of that compound. Firstly, we need to convert 1.5 hectograms to milligrams. Since 1 hectogram = 100 grams and 1 gram = 1000 milligrams, we can say that 1 hectogram = 100,000 milligrams. Therefore, 1.5 hectograms is equivalent to 150,000 milligrams. If each experiment uses 2 milligrams of the compound, the number of experiments that can be conducted is 150,000 milligrams divided by 2 milligrams/experiment, which equals 75,000 experiments. Thus, the science experiment can be repeated 75,000 times.
