Question

solve it for points...​

Answer 1

Number of moles of sucrose = 8 moles

Weight of solvent = 250 g = 250x10^(-3) kg

$Molality = \frac{no \: of \: moles \: of \: solute}{weight \: of \: solvent \: in \: kg} \\ \\ = \frac{8}{250 \times {10}^{ - 3} } \\ = \frac{8 \times 1000}{250} \\ = 8 \times 4 \\ = 32$

Molality = 32

Answer 2

$Molality= </p><p>weightofsolventinkg/</p><p>noofmolesofsolute$

$= </p><p>250×10 </p><p>−3</p><p> </p><p>8$

$= </p><p>250</p><p>8×1000$

$=8×4</p><p>=32</p><p>$
