Answer:
25.34 g of KCI.
Step-by-step explanation:
To calculate the mass of KCI produced, you can use the balanced chemical equation and stoichiometry.
Given the balanced equation:

Since we have 0.34 mol Cl2, we can calculate the amount of K needed:
0.34 mol Cl2 / 1 mol Cl2 = 0.34 mol K
Using the molar mass of KCI (74.55 g/mol), we can calculate the mass of KCI produced:
0.34 mol * 74.55 g/mol = 25.34 g of KCI
So the answer is: 25.34 g of KCI.
