Apharmacy 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.

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.
