Answer 1

$\underline{ \boxed{ \bold{ \rm{ \huge{ \purple{ \mathfrak{Answer}}}}}}} \\ \\ \star \rm \: \red{Given} \\ \\ \implies \rm \: mole \: of \: solute = 1 \\ \\ \implies \rm \: mass \: of \: solvent = 50 \: g = 0.05 \: kg \\ \\ \star \rm \: \red{To \: Find} \\ \\ \implies \rm \: molality \: of \: solution \\ \\ \star \rm \: \red{Calculation} \\ \\ \implies \rm \: \pink{molality = \frac{moles \: of \: solute}{weight \: of \: solvent} } \\ \\ \implies \rm \: molality = \frac{1}{0.05} \\ \\ \therefore \: \underline{ \boxed{ \rm{ \bold{ \orange{molality = 20 \: \frac{mole}{kg} }}}}} \red{ \star}$

☆ Molality (m) is defined as the number of moles of solute per kilogram of solvent.

☆ Molarity is a measurement of the moles in the total volume of the solution, whereas molality is a measurement of the moles in relationship to the mass of the solvent.
