For groups 1 2 3 4 5 6 7 8/0 its quite easy
group one has only one electron in its outer shell thus the valence electron on grp 1 will be 1 and so on eg:grp 2 . 2 electrons in outer shell . then no of valence electron=2 ./for transition metals I recommend you ask your tr because he/she will be able to explain properly but idk if tge pic zbove helps but still

Answer: MM = 16.55 g/mol

Explanation: Freezing point depression is a phenomena that explains why adding a solute to a solvent decreases the solvent freezing point: when a substance begins to freeze, its molecules slows down and rearrange itself forming a solid. If a solute is added, the molecules from the solvent interfere in the formation of the solid. To guarantee the transformation, the solution has to cooled down even more.

Freezing point and molality concentration is related by

$\Delta T=T_{f}_{(solvent)}-T_{f}_{(solution)}=K_{f}.m$
