Marshmallows, on the other hand, are very light and fluffy. Explain why. Because the definitions of both the mole and the atomic mass unit are based on the same reference substance, 12 C, the 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 carbon contains 6 . All spontaneous reactions occur quickly.

Since the amount of Ar is less than 1 mole, the mass will be less than the mass of 1 mole of Ar, approximately 40 g. The molar amount in question is approximately one-one thousandth (~103) of a mole, and so the corresponding mass should be roughly one-one thousandth of the molar mass (~0.04 g): In this case, logic dictates (and the factor-label method supports) multiplying the provided amount (mol) by the molar mass (g/mol): [latex]9.2\times {10}^{-4}\cancel{\text{mol}}\text{Ar}\left(\frac{39.95\text{g}}{\cancel{\text{mol}}\text{Ar}}\right)=0.037\text{g Ar}[/latex]. For given moles of sample, find (a) mass of the sample, (b) molecules in the sample, and (c) atoms in the sample.

While atomic mass and molar mass are numerically equivalent, keep in mind that they are vastly different in terms of scale, as represented by the vast difference in the magnitudes of their respective units (amu versus g). Copper wire is composed of many, many atoms of Cu. To do this, we simply need to multiply the mass of one marshmallow by the Avogadro's number. To put that into perspective, a single marshmallow only weighs about 2 grams. Determine the molar mass of sugar.
