22.4 l of all elements at stp = 1 gram mole of element
 
13.4 l of chlorine = 22.4/13.4 gram mole
 
As per equation 1 gram mole of chlorine produces 2 gram mole of NaCl
 
22.4/13.4 gram mole of chlorine will produce 2x22.4/13.4 gram mole of NaCl
 
1 mole of NaCl = 23+35 = 58 amu
 
2x22.4/13.4 gram mole of NaCl = 2/22.4/13.4   x 58 amu
 
convert amu to kg
