What is the molar mass of chlorine gas, Cl_(2) ? 35.45g/mol 70.90g/mol 34.00g/mol 17.00g/mol

## Step 1: <br />Identify the atomic mass of chlorine (Cl) from the periodic table. The atomic mass of chlorine is approximately \(35.45 \, \text{g/mol}\).<br /><br />## Step 2: <br />Since chlorine gas (\(Cl_2\)) consists of two chlorine atoms, multiply the atomic mass of chlorine by 2 to find the molar mass of chlorine gas.<br /><br />### \(\textbf{Molar mass of } Cl_2 = 2 \times 35.45 \, \text{g/mol}\)<br /><br />## Step 3: <br />Perform the multiplication to calculate the molar mass.<br /><br />### \(\textbf{Molar mass of } Cl_2 = 70.90 \, \text{g/mol}\)
