If the user's Patronus Charm is particularly rare, then the user may be asked an additional question to clarify it. 1 Known choices 2 Known patronus forms 3 Behind ... for each mole of P 4O 10. The molecular masses of these substances tell us that each mole of H 2O weighs 18.0153 g, and each mole of P 4O 10 weighs 283.889 g. Thus the mass ratio of H 2O to P 4O 10 is six times 18.0153 g to one times 283.889 g. 6 × 18.0153 g H 2O 1 × 283.889 g P 4O 10 We can describe this mass ratio using any mass units we want. 6 × 18.0153 g H The main chemical concept that this lab involves is the Law of Conservation of Mass. This states that in a chemical reaction, matter can neither be created or destroyed, or more simply, the mass of the products must equal the mass of the reactants. In this lab, we tested this by putting copper through five different reactions and many phase ...
