To do this, we must first determine the mass of one marshmallow. Which one of the samples has the largest mass? An engagement ring contains a diamond weighing 1.25 carats (1 carat = 200 mg). This is because lead is a metal and marshmallows are made mostly of sugar and air. So one molecule of water will have a smaller mass than one molecule of sugar, since it contains fewer atoms. lead has a molar mass of 207.2 g/mol, while a marshmallow has a molar mass of only 30.0 g/mol. In fact, one cubic centimeter of lead weighs in at a whopping 11 grams. the properties of hydrogen peroxide. For example, the mean molecular weight of water is 18.015 atomic mass units (amu), so one mole of water weight 18.015 grams.
