These terms are functionally the same as molar mass. For example, the GAM of an element is the mass in grams of a sample containing N A atoms and is equal to the element's atomic weight expressed in grams. GFM and GMM are defined similarly. Other terms you may encounter are formula mass and molecular mass. Convert from mass to moles by dividing the mass given by the compound’s molar mass. Convert from moles to molecules by multiplying the number of moles by Avogadro’s number. Solution: A The molecular mass of ethylene glycol can be calculated from its molecular formula using the method illustrated in Example 3.4.1: Molar Mass vs Molecular Mass. Molar mass is the mass of a mole in a substance, and it is calculated using the grams per mole or g/mole. A mole consists of the number of entities present in a substance, like atoms and molecules. Molecular mass is the mass of one molecule or a substance’s mass depending on the atomic weight of carbon-12. Molar Mass The trick: • By definition, this is the mass of 1 mol of a substance (i.e., g/mol) – The molar mass of an element is the mass number for the element that we find on the periodic table – The formula weight (in amuʼs) will be the same number as the molar mass (in g/mol) The reason is that the molar mass of the substance affects the conversion. This site explains how to find molar mass. Using the chemical formula of the compound and the periodic table of elements, we can add up the atomic weights and calculate molecular weight of the substance. Finding molar mass starts with units of grams per mole (g/mol). If you want to know how many moles of a material you have, divide the mass of the material by its molar mass. The molar mass of a substance is the mass in grams of one mole of that substance. This mass is given by the atomic weight of the chemical unit that makes up that substance in atomic mass units (amu). For example, silver has an atomic GytTit. Substitute the known values to calculate the molarity: molarity = 5 / (1.2 × 36.46) = 0.114 mol/l = 0.114 M. You can also use this molarity calculator to find the mass concentration or molar mass. Simply type in the remaining values and watch it do all the work for you.
