$\blue{\underline{ \huge{ \blue{\boxed{ \mathfrak{\fcolorbox{red}{orange}{\purple{Answer}}}}}}}}$

WEIGHT of solute (glucose) = 10 gm

weight of solvent (WATER) = 90 gm

molecular weight of glucose = 180 gm/mol

MOLALITY of solution.....??

$\boxed{ \bold{ \rm{ \pink{molality = \frac{weight \: of \: solute \times 1000}{molar \: mass \: of \: solute \times weight \: of \: solvent} }}}}$

$\rm \: molality = \frac{10 \times 1000}{180 \times 90} \\ \\ \star \: \boxed{ \bold{ \red{ \rm{molality = 0.62 \: m}}}} \: \star$
