This question is a unit conversion question. The key to answering this question is to make certain that you know which conversion factors to use. We'll start with the 1.25 carats. One conversion factor is provided, that one carrot is 200 mg. We can then go from the milligrams to grams. Ultimately, we want to get to the number of atoms of carbon. To get to the number of atoms. We need to go through moles to get to moles. We need to convert the milligrams to grams, 1000 mg in a gram. Then we can go from grams to moles using the molar mass of carbon, Knowing that there's 12.01, 1 g in one mole of carbon. Then, when we know the moles of carbon, we simply multiply by a God rose number to determine the number of carbon atoms And we get 1.25 times 10 to the 22 carbon atoms that are present in 1.25 carats
