1.	If the number of electrons present in 1990 mg of perchlorate ion is a×1023 then the value of ‘a′ would be? Give your answer upto two decimal only. (Given NA=6.02×1023, molar mass of Cl=35.5 g)
Answer» If the number of electrons present in $1990 m g$ of perchlorate ion is $a \times 10^{23}$ then the value of $‘ a^{'}$ would be? Give your answer upto two decimal only. (Given $N_{A} = 6.02 \times 10^{23}$ , molar mass of $C l = 35.5 g$ )
