Kenaikan Titik Didih

Titik didih naik dari 100ºC menjadi 100,1ºC, maka \(\Delta T_B = 1\)

\begin{equation*}
\begin{split}
\Delta T_b & = m \:.\: K_b  \\\\
0,1 & = m \:.\: 0,5  \\\\
m & = \frac {0,1}{0,5} \\\\
m & = 0,2 \text{ molal}
\end{split}
\end{equation*}

\begin{equation*}
\begin{split}
\text{m} & = \frac{\text{n}}{\text{massa}_{\text{ zat pelarut}} \text{ (kg)}}  \\\\
0,2 & = \frac{n}{0,5}  \\\\
n & = 0,2 \:.\: 0,5 \\\\
\text{n} & = 0.1 \text{ mol}
\end{split}
\end{equation*}

\begin{equation*}
\begin{split}
\text{n} & = \frac{\text{m}}{\text{Mr}}  \\\\
0,1 & = \frac{\text{m}}{342}  \\\\
m & = 34,2 \text{ gram}
\end{split}
\end{equation*}
