Answer:
0.350 g of iron
Explanation:
Step 1: Given data
Mass of iron (m): 350 mg
Step 2: Convert the mass of iron to milligrams
In order to convert the mass of iron from grams to milligrams we need a conversion factor. In this case, the conversion factor is 1 g = 1,000 mg.
350 mg Fe × 1 g Fe/1,000 mg Fe = 0.350 g Fe
350 milligrams of iron is equal to 0.350 grams of iron. We conserve the 3 significante figures of the original data.
