Answer 1

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

1. **Convert 250 mg to grams**
(Since there are 1000 mg in a gram, you would convert 250 mg to grams by dividing by 1000. So, 250 mg = 0.250 grams.)

2. **Determine the molecular mass of the compound (active ingredient)**
(You need to know the molecular weight of the active ingredient, which is usually given in grams per mole (g/mol).)

3. **Divide the mass of the medication by the molecular mass you calculated**
(To find the number of moles, you would use the formula: moles = mass (g) / molecular mass (g/mol).)

4. **Derived answer in moles of compound (active ingredient)**
(The result from the previous step provides you with the number of moles of the active ingredient.)

So the ordered steps are:

1. Convert 250 mg to grams
2. Determine the molecular mass of the compound (active ingredient)
3. Divide the mass of the medication by the molecular mass you calculated
4. Derived answer in moles of compound (active ingredient)
