Δ Tf=i× m× Kf =5× 0.01× 1. text86 =9.30× 0.01=0.093° C

Q. The aqueous solution $0.01 M$ of $[C r (N H_{3})_{6}]_{2} [C o (N H_{3}) (N O_{2})_{5}]_{3}$ is expected to have $Δ T_{f}$ equal to Given: $K_{f}$ of $H_{2} O$ is $1.86 K k g m o l^{- 1}$ .

$0.018 6^{\circ} C$

$0.037 2^{\circ} C$

$0.055 8^{\circ} C$

$0.09 3^{\circ} C$

$Δ T_{f} = i \times m \times K_{f}$
$= 5 \times 0.01 \times 1. 86$
$= 9.30 \times 0.01 = 0.09 3^{\circ} C$
