Final answer:
To find the moles of product from the moles of reactant, follow these steps: determine the moles of each reactant, compare the mole ratio of the reactants, calculate the moles of product from the limiting reactant, and convert the moles of product to mass.
Step-by-step explanation:
Solving this type of problem requires that you carry out the following steps:
- Determine the number of moles of each reactant.
- Compare the mole ratio of the reactants with the ratio in the balanced chemical equation to determine which reactant is limiting.
- Calculate the number of moles of product that can be obtained from the limiting reactant.
- Convert the number of moles of product to mass of product.
For example, let's say we have the reaction: 2 A + 3 B → 4 C
If you have 2 moles of A and want to find the moles of product (C), you would first compare the mole ratios: 2 moles A: 3 moles B and 2 moles A: 4 moles C. Since the ratio between A and C is 2:4, the mole ratio is 1:2. So if you have 2 moles of A, you would expect to produce 4 moles of C.
Remember to always balance the chemical equation and convert between moles using the mole ratio!
