Suppose a piece of silver jewelry contains 7.78×1022 atomsatoms of silver (AgAg).

**Understanding Counting Units in Chemistry** **Common Counting Units:** - 1 dozen = 12 - 1 score = 20 - 1 ream = 500 - 1 gross = 144 The mole (mol) is a counting unit used by chemists, similar to how a dozen is used by bakers: \[ 1 \, \text{mol} = 6.022 \times 10^{23} \] --- **Problem Context:** Suppose a piece of silver jewelry contains \( 7.78 \times 10^{22} \) atoms of silver (Ag). **Part A:** - **Objective:** Calculate how many dozens of silver atoms are in this piece of jewelry. - **Instructions:** Express your answer numerically in dozens. **Hints for Solving:** 1. **Hint 1:** Learn how to convert between items and dozens. 2. **Hint 2:** Understand the relationship between the given value and the answer. **Input Method:** An interactive keyboard for special characters is provided for entering answers. --- This educational content is designed to enhance understanding of counting units in chemistry and help solve related problems effectively.
