Final answer:
To determine moles of reactants and products, convert given masses to moles using their molar masses, then apply the stoichiometry of the balanced equation to find moles of products.
Step-by-step explanation:
When determining the number of moles of reactants and products in a chemical reaction, we need to relate the given masses to moles using the molar mass of each substance. As the given information is incomplete, we will use some general principles and a hypothetical example to explain this process.
For instance, let's consider a balanced chemical equation, A + B → C. If we have 114 g of A and 230 g of B, we would first find the molar mass of both A and B and then convert their masses to moles. Once the reaction completes, the moles of products formed depend on the initial moles of reactants and the stoichiometry of the reaction. If the mole ratio of A to B to C is 1:1:1, then the reaction will produce an equal number of moles of C to the limiting reactant.
In some situations, such as the conversion of gas volume to moles, we can use the ideal gas law or the molar volume of a gas at standard temperature and pressure (STP), which is 22.4 L/mol, to find the amount of gas produced or reacted.
