Question

how to find molecular weight of sodium chloride??

Answer 1

Answer is 58.5
Explanantion:

Atomic weight of sodium is 23
Atomic weight of chloride is 35.5
Molecular weight of NaCl is 23 + 35.5=58.5
So one mole of sodium chloride is 58.5 grams.

Answer 2

Na=2,8,1

Cl=2,8,7

Molecular wt.=11×1+2×17=45g.

I'm not sure of this...just like that done...
