The medicine is supplied in the amount 3,000,000 mcg. How many grams are in the medicine? Show all work using dimensional analysis
1 g = 1,000,000 mcg
To convert mcg to grams, we can set up a conversion factor:
(3,000,000 mcg) * (1 g / 1,000,000 mcg) = 3 g
Therefore, there are 3 grams in the medicine.
To convert mcg (micrograms) to grams, we can use the following conversion factor:
1 gram = 1,000,000 micrograms
Let's set up the dimensional analysis using this conversion factor:
3,000,000 mcg * (1 gram / 1,000,000 mcg)
Now, let's solve the equation step by step:
Step 1: Cancel out the units by multiplying across the numerator and denominator:
= 3,000,000 * 1/1,000,000 mcg * gram
= 3 grams
Therefore, there are 3 grams in the medicine.
