Well we are not able to see the internal structure of the Earth directly because we can't get at it! The thinnest crust is under the oceans but even that is around 7kms thick, way deeper than we can drill. We have to use indirect methods like earthquakes, and infer the structure from the way the pressure and shear waves produced travel through the Earth.

The answer is 62.00 g/mol.
Solution:
Knowing that the freezing point of water is 0°C, temperature change Δt is
Δt = 0C - (-1.23°C) = 1.23°C
Since the van 't Hoff factor i is essentially 1 for non-electrolytes dissolved in water, we calculate for the number of moles x of the compound dissolved from the equation
Δt = i Kf m
1.23°C = (1) (1.86°C kg mol-1) (x / 0.105 kg)
x = 0.069435 mol
Therefore, the molar mass of the solute is
molar mass = 4.305g / 0.069435mol = 62.00 g/mol
Whats the question? I need to know to help....
