There are so many rock types around! Though, with all the rock types.. there are a few that we study within grade school and such. These types of rocks are,
-Igneous // Igneous rock is formed through the cooling and solidification of magma or lava.
-Sedimentary // Sedimentary rocks are types of rock that are formed by the deposition and subsequent cementation of mineral or organic particles on the floor of oceans or other bodies of water at the Earth's surface.
-Metamorphic // The original rock is subjected to heat and pressure, causing profound physical or chemical change.

Answer:
T = 11.4°C
Explanation:
Given that:
weight of solute w (glucose) = 12 g
weight of solvent W (acetic acid) = 50 g
Molar depression constant of solvent (Kf)= 3.90°C/m
Temperature of solvent freezing point T₀ = 16.6°C
Temperature of solution freezing point Tₓ = (T₀ -T) = ???
Molar mass of solute (glucose) = 180.2 g/mol
Using the expression;
(T₀ -T) = 




-T = -16.6 °C + 5.2 °C
- T = -11.4°C
T = 11.4°C
∴ The freezing point of the solution is said to be = 11.4°C
