How many moles of glycine molecules are contained in 28.35 g of glycine? The molar amount of a substance may be calculated by dividing its mass (g) by its molar mass (g/mol): The factor-label method supports this mathematical approach since the unit g cancels and the answer has units of mol:, [latex]4.7\cancel{\text{g}}\text{K}\left(\frac{\text{mol K}}{39.10\cancel{\text{g}}}\right)=0.12\text{mol K}[/latex]. A methane molecule is made from one carbon atom and four hydrogen atoms. One mole of glycine, C2H5O2N, contains 2 moles of carbon, 5 moles of hydrogen, 2 moles of oxygen, and 1 mole of nitrogen: The provided mass of glycine (~28 g) is a bit more than one-third the molar mass (~75 g/mol), so we would expect the computed result to be a bit greater than one-third of a mole (~0.33 mol). which sample has the largest mass 1 mole of marshmallows One 55-gram serving of a particular cereal supplies 270 mg of sodium, 11% of the recommended daily allowance. One mole of a substance is equal to the amount of that substance that has a mass of 6.022 x 10^23 atoms or molecules. The most important factor is the composition of each substance.
