The mass of the ethylene glycol used is 14.26 g
<h3>What is the freezing point?</h3>
The freezing point is the temperature at which a liquid is converted to a solid.
Given that;
ΔT = 0.0°C - ( -4.3°C) = 4.3°C
ΔT = 4.3°C
But we know that
ΔT = k m i
m = ΔT/k i
m = 4.3°C/1.86 °C/m * 1
m = 2.3 m
Now;
Let the mass of ethylene glycol be m
Molar mass of ethylene glycol = 62 g/mol
Mass of solvent = 100.0 g or 0.1 Kg
Then;
2.3= m/62/0.1
2.3 = m/62 * 0.1
m = 2.3 * 62 * 0.1
m = 14.26 g

Answer: It's C
Explanation:
A solution is defined as a homogeneous mixture in which solute particles are evenly distributed into the solvent.
A solution is a clear solution whose particles cannot be separated out as they are all present in same state.
On the other hand, a mixture in which particles are unevenly distributed into the solvent is known as a heterogeneous mixture.
For example, sand in water is a heterogeneous mixture.
Particles of a heterogeneous mixture can be separated out generally through filtration. This is because these particles are not present in same state.
Thus, we can conclude that the statement a mixture having a uniform composition where the components can't be seen separately and all components are in the same state, best describes a solution.
The answer is 2.18 moles MgSi03.
The answer would be B, double covalent bond... I would think.
