$question \: = \: the \: molar \: \\ elevation \: constant \: for \\ \: water \: is \: 0.56 \: K \: kg \\ \: mol^-1 \: .The \: boiling \: \\ point \: of \: a \: solution \\ \: made \: by \: dissolving \\\: 6.0 \\ \: grams \: of \: urea \\ \: (NH2CONH2) \: in \\ \: 200 \: grams \: of \: water \: is$

$by \: using \: the \: formula \\ Δtb \: = \: kbm$

$0.56 \: \times \: 6 \times \: 1000 \\ \div \: 60 \: \times \: 200 \\ = 0.56 \: \times \: 30 \div 60$

$0.56 \: \times \: 1 \div 2 \\ = Δtb \: = \: 0.28$

$100.28 K$

Hope it helps ☺️
