The formula to calculate the Moles from Milligrams is:
\[ \text{Moles} = \frac{\text{Mg}}{\text{MW}} \]
Where:
Mg to moles refers to the conversion of the mass of a substance (measured in milligrams) to the amount of substance (measured in moles). This conversion is based on the molecular weight of the substance, which is the sum of the atomic weights of all the atoms in a molecule of the substance. One mole of a substance contains Avogadro's number (approximately \(6.022 \times 10^{23}\)) of molecules or atoms of that substance. Therefore, to convert milligrams to moles, you divide the mass of the substance in milligrams by its molecular weight in milligrams per mole.
Let's assume the following values:
Using the formula to calculate the Moles:
\[ \text{Moles} = \frac{500}{180} \approx 2.78 \text{ mol} \]
The amount of substance is approximately 2.78 moles.
