    Answer:

    84.8%

    Explanation:

    Step 1: Given data

    Bob measured out 1.60 g of Na. He forms NaCl according to the following equation.

    Na + 1/2 Cl₂ ⇒ NaCl

    According to this equation, he calculates that 1.60 g of sodium should produce 4.07 g of NaCl, which is the theoretical yield. However, he carries out the experiment and only makes 3.45 g of NaCl, which is the real yield.

    Step 2: Calculate the percent yield.

    We will use the following expression.

    %yield = real yield / theoretical yield × 100%

    %yield = 3.45 g / 4.07 g × 100% = 84.8%
