If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight. The percentage by weight of any atom or group of atoms in a compound can be computed by dividing the total weight of the atom or group of atoms in the formula by the formula weight and multiplying by A common request on this site is to convert grams to moles.

To complete this calculation, you have to know what substance you are trying to convert. The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass. Formula weights are especially useful in determining the relative weights of reagents and products in a chemical reaction. These relative weights computed from the chemical equation are sometimes called equation weights.

We use the most common isotopes. And even then, it may take at least 5 minutes of constant swishing around to mix unless you have a sonicator. Expect the volume of the water to almost double. When I weighed out "32 g" of urea in "25 mL" of water, it became about "50 mL" due to displacement.
