"/>Gas stoichiometry deals with reactions involving gases, where the gases are at a known temperature, pressure, and volume and can be assumed to be ideal gases. For gases, the volume ratio is ideally the same by the ideal gas law, but the mass ratio of a single reaction has to be calculated from the molecular masses of the reactants and products.Calculate the mass ratio of CH 4 to O 2 required for complete combustion. Solution: This is just the ratio of the molar mass of CH 4 (16 g) to that of two moles of dioxygen (2 x 32 g) Thus (64 g) / (16 g) = 4/1 = 4.0.

From this information, you can figure out how many electrons it needs to gain or lose to achieve a full outer shell. Groups 1-3 (metals) will LOSE electrons. Groups 5-7 (non-metals) will GAIN electrons. Group 4 can do either.

One mole of a substance contains the same number of the stated particles, atoms, molecules, or ions as one mole of any other substance. One mole contains 6.02 x 1023 particles (e.g. atoms, ions, molecules); this number is known as the Avogadro Constant.
