Amole (abbreviated mol) is defined as an exact number of objects: 6.02 × 1023 (avogadro’s number). you can have 1 mole of an atom, a molecule, or any other object, such as eggs or books. one mole of an object equals 6.02 × 1023 of that object. the table shows the “molar ratios” of some of the products from the miller h2s experiment. in a molar ratio, each unitless value is expressed relative to a standard for that experiment. here, the standard is the number of moles of the amino acid glycine, which is set to a value of 1.0. for instance, serine has a molar ratio of 3.0 × 10–2, meaning that for every mole of glycine, there is 3.0 × 10–2 mole of serine present in the sample. what is the molar ratio of methionine to glycine in the samples?
