Answer:

m = 0.122 m

Explanation:

Molality(m): A measure of the number of moles of solute in a solution corresponding to 1 kg or 1000 g of solvent.

\mathrm{Molality\:Formula}:\quad \mathrm m =  \dfrac{ mole\:of\:solute  }{ mass\:of\:solvent\:in\:kg  }

\mathrm m =  \dfrac{ mole}{ kg  }

\mathrm{Substitute\:the\:numbers\:into\:the\:"Molality\:Formula"}

\mathrm m =   \dfrac{ 0.250  }{ 2.05  }

\mathrm{Divide\:0.250\:by\:2.05\:and\:get\:0.12195122}

\mathrm m =   {0.12195122}

\mathrm{Round\:to\:the\:nearest\:thousandths\:place}

\mathrm m =   0.122
