A student mixes 0.10 mol of AgNO₃ and 0.20 mol of NaCl. How many moles of AgCl can form?
A.0.10 mol
B.0.20 mol
C.0.30 mol
D.0.050 mol
Explanation
Core Concept
Ag⁺ and Cl⁻ combine 1:1. AgNO₃ (0.10 mol) limits the reaction, so at most 0.10 mol of AgCl forms; the extra NaCl stays dissolved.
Correct Answer
A0.10 mol
