To solve this problem, it would be helpful to know the density of 1 block Density is defined as the mass of the substance per volume. From the example given, The density of the block is (7g)/(15.625 units^3) or 0.448 g/units^3. So, if a block is added, the new mass is 7g + 7g = 14 g And the volume 14 g /(density) = 1 unit^3

A 0.89 m aqueous solution of an ionic compound with the formula mx has a freezing point of -3.0 ∘c . van't hoff factor?
BigorU [14]

Answer is: V<span>an't Hoff factor (i) for this solution is 1,81.
Change in freezing point from pure solvent to solution: ΔT =i · Kf · b.
Kf - molal freezing-point depression constant for water is 1,86°C/m.
b -  molality, moles of solute per kilogram of solvent.
</span><span>b = 0,89 m.
ΔT = 3°C = 3 K.
i = </span>3°C ÷ (1,86 °C/m · 0,89 m).

i = 1,81.
