What mass of metallic silver can form from 1.147 g of copper metal according to equation b?
Arisa [49]

Answer:

        \large\boxed{\large\boxed{3.894g}}

Explanation:

From similar question, equation (b) is

Molecular Equation:

  • Cu(s) + 2AgNO₃(aq) → Cu(NO₃)₂(aq) + 2Ag(s)

Net Ionic Equation:

  • Cu(s) + 2Ag⁺(aq) → Cu²⁺(aq) + 2Ag(s)

<u>1. Mole ratio:</u>

       \dfrac{2molAg(s)}{1molCu(s)}

<u>2. Convert 1.147 g of Cu(s) to moles:</u>

  • Atomic mass of Cu: 63.546g/mol

  • Number of moles = mass in grams / atomic mass

  • Number of moles = 1.147 g / 63.546 g/mol = 0.01805 mol Cu(s)

<u />

<u>3. Calculate the moles of Ag(s):</u>

    0.01805molCu(s)\times \dfrac{2molAg(s)}{1molCu(s)}=0.03610molAg(s)

<u />

<u>4. Convert 0.03610 mol Ag(s) to grams:</u>

  • Atomic mass of Ag(s) = 107.868g/mol

  • Mass = 0.03610mol × 107.868g/mol = 3.894g
