Question

The number of moles of Cu produced in this reaction is

Answer 1

I don’t have the reaction or the amounts you were given. To answer exactly I need the balanced chemical equation and the quantities (grams or moles) of the reactants.

Here’s how you can find the number of moles of Cu produced — follow these steps (and paste your numbers if you want me to compute it):

1. Write the balanced chemical equation.
- Example common displacement: Cu^2+ + Zn -> Zn^2+ + Cu (1:1 stoichiometry)

2. Convert all given masses to moles (moles = mass / molar mass) or use the moles given directly.

3. Identify the limiting reagent by comparing the mole ratio of reactants to the stoichiometric ratio from the balanced equation.
- For the example Cu^2+ + Zn -> Cu + Zn^2+, 1 mol Zn reduces 1 mol Cu^2+ to give 1 mol Cu.
- If you have n(Cu^2+) and n(Zn), the limiting reagent is the smaller of n(Cu^2+) and n(Zn).

4. Use stoichiometry to find moles of Cu produced:
- Multiply moles of the limiting reagent by the stoichiometric coefficient for Cu.

5. (Optional) Convert moles of Cu to grams if required (mass = moles × 63.546 g·mol−1).

Quick numeric example:
- If you have 1.50 mol Cu^2+ and 1.20 mol Zn, reaction is 1:1 so Zn is limiting → Cu produced = 1.20 mol.

If you paste the reaction and the amounts you have, I’ll compute the moles of Cu for you.
