B. the molar mass is 71.0 g

A. The molar mass is 35.5 g (according to the periodic table)
The molar mass is generally the mass of one mole of that substance (chlorine). One mole of chlorine equals to 6.02214×10^23 atoms of chlorine. Be careful not to confuse molar mass with molecular mass, though. Molecular mass of chlorine would be mass of ONE chlorine atom. So, C. is definitely wrong as it is describing molecular mass of chlorine, not molar.

Sorry, George.
Cl2, two atoms per molecule, formula mass 71.0. 35.5 is atomic mass not molar mass.

I'm Anthony. I lost 75 pounds and shed my high school nickname Pudgy. Our family has a tragic history of cardiac disease and rheumatoid arthritis. I am proud to say that family tradition ends with me. I know I have broken the cycle and will never have to be faced with those illnesses. Thank, you have changed my life.
