For an ideal solution containing a nonvolatile solute,which of the following expressions is correctly represented?

$\begin{array}{1 1}-\Delta T_f=K_fm\;with\;K_f=M_1RT_f^{*2}/\Delta_{fus}H_m\\-\Delta T_f=K_fm\;with\;K_f=RT_f^{*2}/M_1\Delta_{fus}H_m\\-\Delta T_f=K_fm\;with\;K_f=M_1T_f^{*2}/R\Delta_{fus}H_m\\-\Delta T_f=K_fm\;with\;K_f=\Delta_{fus}H_m/M_1RT_f^{*2}\end{array} $

Answer : $-\Delta T_f=K_fm\;with\;K_f=M_1RT_f^{*2}/\Delta_{fus}H_m$
The correct expressions are $-\Delta T_f=K_fm$ where $K_f=M_1RT_f^{*2}/\Delta_{fus}H_m$
