Molarity =  Moles/Liter 
Use the molecular atomic mass of NaCl to convert from grams to moles. 
Molecular mass of NaCl is the sum of its atomic masses. Look at the periodic table to find these. Na is 23 g/mol and Cl is 35.5 g/mol , 
so NaCl = 23 + 35.5 = 58.5 g/mol 
multiply to cancel out grams
76 g NaCl * (1mol / 58.5 g NaCl) = 1.3 mol NaCl 
over 1 Liter is just 1.3 M NaCl 
Hope this helps!
