How does the amu relate to that of a mole
WebThe AMU is a mass unit equal to the weight of one proton or neutron. A mole is 6.02 * 10 23 things. A mole of hydrogen molecules is 6.02 * 10 23 hydrogen molecules just like a dozen mole of hydrogen molecules is 12 hydrogen molecules. The reason 6.02 * 10 23 is used is because the AMU is 6.02 * 10 23 times smaller than the gram. WebAug 31, 2016 · One mole of a compound has a mass in grams equal the molecular weight of the compound expressed in amu and contains 6.022 × 10 23 molecules of that compound. Now, I perfectly understand the second part of the sentence. 1 mole of compound has 6.022 × 10 23 molecules.

WebThe molar mass of any substance is numerically equivalent to its atomic or formula weight in amu. Per the amu definition, a single 12 C atom weighs 12 amu (its atomic mass is 12 amu). A mole of 12 C atoms weighs 12 g (its molar mass is 12 g/mol). This relationship holds for all elements, since their atomic masses are measured relative to that of the amu … WebThe atomic mass of an element can be used to convert Avogadro's number to the number of moles of that element. What is the molar mass of acetic acid (HC2H3O2)? (NOTE: H = …
