Explain why chlorine has relative atomic mass of about 35.5 u?

Explain 'relative atomic mass' .

The following question refer to one gram molecular mass of chlorine gas : If the relative atomic mass of chlorine is 35.5, what will be the mass of one mole of Cl_(2) gas ?

The two isotopes of chlorine have atomic mass 35 u and 37 u. Should they be placed in separate slots in the periodic table ?

The two isotopes of chlorine have atomic masses 35 u and 37 u. Should they be placed in the same slot in the periodic table?

Two types of atoms of chlorine have atomic masses 35 and 37, then why is the atomic mass of chlorine taken as 35.5?

What is the mass in grams of a single atom of chlorine ? (Atomic mass of chlorine = 35.5)

Chlorine has two isotopes of atomic mass units 34.97 u and 36.97 u . The relative abundances of these two isotopes are 0.735 and 0.245 respectively. Find out the average atomic mass of chlorine.
