Question

A pharmacy uses 5×10−3 liter of an active ingredient in one dose of a medication. The active ingredient comes in a 1.5-liter bottle. How many doses of the medication can be made with one bottle of the active ingredient? Write your answer in standard form.

Answer 1

We can know the number of doses a one bottle of medication by dividing 1.5 Liters with 5 x 10^-3. First we need to make 5 x 10^-3 into decimal form which makes 0.005 L. Then dividing the 1.5 L with 0.005 L will give us how many dose of 0.005 L can make with 1.5 L of medication.
1.5 / 0.005 = 300 doses. To write it in standard form 300 is 3 x 10^2.
