Avogadro’s law states that equal volumes of gas, at the same pressure and temperature, have the same amount of molecules. This applies to the lab in that it allows for the verification of the molar volume of hydrogen at standard temperature and pressure once temperature, pressure, and volume are all accounted for. Dalton’s law of partial pressure is another theory that was explored in this lab. It states that the total pressure of a mixture of gases is the sum of the partial pressures of the individual gases. This law makes it possible for the partial pressure of the water vapor to be removed from the total pressure of the gases in the eudiometer tube to yield the partial pressure of hydrogen gas. Molar volume is the volume occupied by one mole of a gas, in this case, hydrogen gas. Molar volume relates to the lab as the entire purpose of this lab is to find the molar volume of hydrogen gas at STP. The ideal gas law describes a relationship between pressure (P), volume (V), the number of moles (n), temperature (T), and the universal gas constant (R) where PV = nRT. This ideal gas law is essential to the lab as it explains the relationships between the different measurements of a gas and reduces into the combined gas law. The combined gas law is a relation where the number of moles of gas is constant, thus leaving the variables of pressure, volume, and temperature. When comparing the same substance under different conditions, the combined gas law can be mathematically written as (P"1" V"1" )/T"1" = (P"2" V"2" )/T"2" . Since the conditions of the experiment were not at standard temperature and pressure, the combined gas law is required in order to calculate the corresponding volume of hydrogen gas at STP. Single displacement reactions were also
