Answer: the mass of 3.01 atoms of chlorine is 35.46/2 = 17.73 g.
Explanation: hope its correct
step by step: molar mass: (2 x 35.46) g/mol = 70.92 g/mol
1 mole chlorine = 6.02 x 10^23 molecules of chlorine.
Mass of 6.02 x 10^23 molecules chlorine = 70.92 g
Mass of 3.01 x 10^23 molecules chlorine = 70.92 x(3.01 x 10^23)/(6.02 x 10^23)g
= 35.46 g
