Question

how many molecules are in 6 cacl₂?
6
4
12
1

Explanation:

Step1: Interpret the coefficient

The number written before the chemical formula $\text{CaCl}_2$ is the coefficient, which represents the number of discrete molecules (or formula units, for ionic compounds) of the substance.

Step2: Identify the given coefficient

The given formula is $6\ \text{CaCl}_2$, where the coefficient is 6. This directly tells us the number of $\text{CaCl}_2$ formula units.

Answer:

6
