### (where n is number of moles, C concentration and V is volume). In most cases concentration is given in moles per liter of solution (molarity, denoted here as M), but sometimes it can be also given as normality.

- One mole of CO 2 contains one mole of carbon atoms and two moles of oxygen atoms. The mass of a mole of atoms of an element is called the atomic mass and is given in the periodic table, such as the one on the back cover of this manual and the one you will get on the data sheet in your exam. The atomic masses of carbon and oxygen are 12.01 and 16.00 g respectively. The molecular mass of a
