Final answer:
To convert 8,500,000 micrograms to grams, multiply by the conversion factor (1 gram/10^6 micrograms), which will cancel out the 'micrograms' unit and give the result in grams. Therefore, 8,500,000 micrograms is equal to 8.5 grams.
Step-by-step explanation:
The factor label method is a way to convert units using the multiplication of fractions that are equal to 1 called conversion factors. To convert 8,500,000 micrograms (µg) to grams (g), you need to know the relationship between these two units. One microgram is equal to 10-6 grams, which can also be written as 1 µg = 10-6 g. Using this conversion factor, you can set up the problem like this:
8,500,000 µg × (1 g/106 µg) = 8.5 g
Here, the 'µg' units will cancel out, and you will be left with the units in grams, which is what you are trying to find.
So, 8,500,000 micrograms is equal to 8.5 grams when using the factor label method.
