Question

what is the molar mass of cl2?

Explanation:

Step1: Recall molar mass of Cl

The molar mass of a single chlorine (Cl) atom is approximately $35.453\ \text{g/mol}$.

Step2: Calculate molar mass of Cl₂

For $\text{Cl}_2$, we have 2 chlorine atoms. So we multiply the molar mass of one Cl atom by 2: $2\times35.453\ \text{g/mol} = 70.906\ \text{g/mol}$.

Answer:

70.906 g/mol (corresponding to the option with 70.906 g/mol, e.g., if the red box option is D. 70.906 g/mol, then D. 70.906 g/mol)
