To convert millimoles (mmol) to moles (mol), you need to remember that 1 mmol is equal to 0.001 mol. This means that you can convert millimoles to moles by dividing the number of millimoles by 1000.
So, to convert 3.66 mmol to mol, you would calculate:
3.66 mmol × (1 mol / 1000 mmol) = 0.00366 mol
Thus, 3.66 mmol is equal to 0.00366 mol.
