1. Calculate the number of moles present in:  ( Na=23, Cl=35.5

(i)0.23 g of Sodium atoms

 =   Cloze (2): JXUwMDY4JXUwMDFlJXUwMDFlJXUwMDAx moles

(ii) 0.23 g of Chlorine atoms

 Moles =   Cloze (3): JXUwMDY4JXUwMDFlJXUwMDFlJXUwMDAwJXUwMDA2JXUwMDAz moles 

(iii) 0.23 g of Chlorine molecules

 Moles =      = Cloze (5): JXUwMDY4JXUwMDFlJXUwMDFlJXUwMDAwJXUwMDAzJXUwMDAx moles 

(iv) 0.23 g of dilute sulphuric(VI)acid

           Moles   = Cloze (7): JXUwMDY4JXUwMDFlJXUwMDFlJXUwMDAwJXUwMDAyJXUwMDAx moles
