You should take the prednisone pack exactly as it was prescribed by your physician. If the pain returns when you have completed the course of prednisone, call your physician.
In addition to mass, we can also measure how big a molecule is. A water molecule is about 0.27 of a nanometer across. DNA is about 2 nanometers across and can stretch out to meters in length. Amazing, when you think about that length of DNA being stuffed inside a cell. But that is because it is so thin, about 1/1,000,000,000 as thick as it is long.
A mol is an expression of the molair weight of a molecule, derived from the weight of a hydrogen molecule, which is 1 mol. Hydrogen has a relative atomic mass of 1 g/ mol and oxygen has a relative atomic mass of 16 g/ mol. Water consists of one oxygen atom and two hydrogen atoms. This means that the mass of a water molecule is 1g + 1g + 16g = 18 g/ mol. When the number of moles of water is known, one can calculate how many grams of weight this is, by using the molar weight of water. The molair weight of separate atoms can be found in the periodic table of Mendelejef.
