Answer 1

To determine the number of moles in a dose of medication that contains 250 mg of an active ingredient, you should follow these steps in the correct order:

1. **Convert 250 mg to grams**
(This is the first step since you need to convert milligrams to grams for consistency in units.)

2. **Determine the molecular mass of the compound (active ingredient)**
(Next, you need to know the molecular mass of the active ingredient to perform the calculations.)

3. **Multiply the mass of the medication times the molecular mass you calculated**
(Now you will calculate the total mass in grams multiplied by the molecular mass.)

4. **Derived answer in moles of compound (active ingredient)**
(Finally, you will divide the total mass of the active ingredient by its molecular mass to find the number of moles.)

So, the correct order is:
1 → 3 → 4 → 2
