The number of unpaired electrons can be determined as follows:
As we know that, magnetic moment $=\sqrt{n(n+2)}$
$5.9=\sqrt{n(n+2)}$
On squaring both sides, the above equation becomes
$(5.9)^{2}=n^{2}+2 n$
$n^{2}+2 n-35=0$
On solving the above equation, we get $n=5$
$1\, L \,of\, X + Excess\, of\, AgNO_3 \rightarrow Y\, mol\, of\, ppt.$
$1\, L\, of\, X + Excess\, of\, BaCl_2 \rightarrow Z\, mol\, of\, ppt.$
તો $Y$ અને $Z$ અનુક્રમે ............... થશે.
($A$ અને $B$ એકદંતીય લિગેન્ડ છે.)
