So one molecule of water will have a smaller mass than one molecule of sugar, since it contains fewer atoms. The given number of moles is a very small fraction of a mole (~10-4 or one-ten thousandth); therefore, we would expect the corresponding mass to be about one-ten thousandth of the molar mass (~0.02 g).

First, convert the grams to moles using the molar mass and then use Avogadro's number to find the number of molecules: This calculation tells you that there are 2.1 x 10 22 molecules of NaCl in 2 grams of NaCl. (B) 16 g of oxygen (molar mass 32) corresponds to 0.5 moles of molecules or N number of atoms where N is the Avogadro's number . 1 dm 3 is the same as 1000 cm 3, so the value in cubic centimetres needs to be divided by 1000. One of these amino acids is glycine, which has the molecular formula C2H5O2N. This is because marshmallows are not very dense. Avogadro's number is a constant that is equal to the number of atoms or molecules in one mole of a substance. Lead is much heavier than marshmallows. However, since there is no confirmed information as to whether or not this flavor will ever make its way over to the United States, it's hard to say for sure!
