검증된 단계별 안내1
Understand the relationship between moles and millimoles: 1 mole (mol) is equal to 1000 millimoles (mmol).
Write this relationship as an equality: \(1\ \text{mol} = 1000\ \text{mmol}\).
To convert from millimoles to moles, set up a conversion factor that cancels out millimoles and leaves moles.
Since you want to convert mmol to mol, place moles in the numerator and millimoles in the denominator: \(\frac{1\ \text{mol}}{1000\ \text{mmol}}\).
This conversion factor means you multiply the number of millimoles by \(\frac{1\ \text{mol}}{1000\ \text{mmol}}\) to get the amount in moles.
