Multiple Choice 10 points What is the molar mass of Cl_(2) 17g/mol 35.5g/mo 71.0g/mol 89g/mol

The molar mass of a substance is the mass of one mole of that substance. It is usually expressed in grams per mole (g/mol). The molar mass of chlorine (Cl) is 35.5 g/mol. Since the molecule in question is $Cl_{2}$, which means it has two chlorine atoms, we need to multiply the molar mass of chlorine by 2 to get the molar mass of $Cl_{2}$.<br /><br />So, the molar mass of $Cl_{2}$ is 71.0 g/mol.<br /><br />Therefore, the correct answer is: $71.0g/mol$.
