Someone answer the limited regent...

Answer:
20 g Ag
General Formulas and Concepts:
Chemistry - Stoichiometry
Chemistry - Atomic Structure
Explanation:
Step 1: Define
[RxN] Cu (s) + AgNO₃ (aq) → CuNO₃ (aq) + Ag (s)
[Given] 10 g Cu
Step 2: Identify Conversions
[RxN] 1 mol Cu = 1 mol Ag
Molar Mass of Cu - 63.55 g/mol
Molar Mass of Ag - 197.87 g/mol
Step 3: Stoichiometry
[tex]10 \ g \ Cu(\frac{1 \ mol \ Cu}{63.55 \ g \ Cu})(\frac{1 \ mol \ Ag}{1 \ mol \ Cu} )(\frac{197.87 \ g \ Ag}{1 \ mol \ Ag} )[/tex] = 16.974 g Ag
Step 4: Check
We are given 1 sig fig. Follow sig fig rules and round.
16.974 g Ag ≈ 20 g Ag
