We are perfectly used to the determination of the mass of a macroscopic object. Commonly, we use scales for this type of measurement. Mass is a physical quantity that is independent of local gravitation. However, their mass is still the same independent of where they are. The unit of mass is the kilogram kg. The masses of atoms and molecules are extremely small, by far beyond our imagination. The amount of The mole is defined as a number of particles, 6. To calculate the mass of a single atom of carbon, we just need to divide the molar mass of Doing so yields 1. Large molecules, in particular macromolecules are composed of many atoms. Still, even a large molecule like insulin, C H N 65 O 75 S 6, has a mass of just 9. To illustrate the tiny size of a molecule, one may compare the proportions of a molecule of ascorbinic acid vitamin C, ca. We find that ratio is about 1: Now, the proportion of this grapefruit to Earth is also about Thus, weighing is no more feasible. So let us go down by several orders of magnitude: 1 ng nanogram, one billionth of a g or 10 —9 g1 pg 10 —12 g1 fg femtogram, 10 —15 g1 ag attogram, 10 —18 g. And even the attogram is roughly by a factor of larger than the mass of a single molecule of insulin. The so-called unified atomic mass unit symbol u serves to quantify atomic and molecular mass. Provided we know the mass number of an atom, its mass can be calculated quite accurately by multiplying this mass number by 1 u. It may appear disappointing to some degree that this simple calculation does not yield the exact mass, but this may even be exploited to our advantage for formula determination based on measuring accurate mass. So one carbon atom 12 C possesses a mass of 12 u or 1. Clearly, using atomic mass units comes in more handy than using kilograms. They are nonetheless far beyond our imagination and it definitely requires some completely different approach for their accurate measurement: mass spectrometry! A note concerning gigantic and minuscule numbers in science. Nature comprises enormous orders of magnitude. Factors of billions are common in natural sciences. Atmospheric pressure, for example, is mbar while high vacuum is 10 —6 mbar, one billionth of atmospheric pressure. Due to the formula C 12 H 22 O 11a sugar molecule saccharose has a mass of Anything outside our daily reality carbon dating formula appear as something very special or even unreal. Just accept these orders of magnitude as something natural.
