Final answer:
When excess zinc is added to a 50 ml solution of 2.0 M CuSO₄, the expected amount of solid copper to be produced, according to the stoichiometry of the balanced chemical reaction, is 6.355 grams.
Step-by-step explanation:
When excess zinc is added to a 50 ml solution of 2.0 M CuSO₄, a displacement reaction occurs where zinc replaces copper in the solution, resulting in solid copper being produced. The reaction is presented by the equation:
CuSO₄ (aq) + Zn(s) → Cu(s) + ZnSO₄ (aq)
The first step is to calculate the number of moles of CuSO₄ in the 50 ml solution. Since we know the concentration is 2.0 M, we can determine that there are:
2.0 moles/liter × 0.050 liters = 0.1 moles of CuSO₄
Next, using the stoichiometry of the reaction, which is a 1:1 ratio, we can deduce that 0.1 moles of solid copper should also be produced. Using the molar mass of copper (63.55 g/mol):
0.1 moles × 63.55 g/mol = 6.355 g
Therefore, 6.355 grams of solid copper should be produced if the reaction goes to completion.
