Answer: ethylene glycol (molar mass = 62.07 g/mol)
Explanation:
Depression in freezing point :
Formula used for lowering in freezing point is,
or,
where,
= change in freezing point
= freezing point constant=
m = molality
Given mass of solute = 0.807 g
Molar mass of solute=? g/mol
weight of solvent in kg= 11.6 g=0.0116 kg
Thus the solute is ethylene glycol which has same molecular mass as calculated, i.e 62.07 g/mol.

Answer: False
Explanation:
Metal oxides that dissolve in water, react with water to form basic solutions.
Nonmetal oxides react with water to form acidic solutions.
False. The nature of the solution actually depends on the type of metal oxide. Not all metal oxides will make water acidic when mixed.
The statement that mixing metal oxide with water will result in an acidic solution is generally false.
Actually, the nature of the solution (acidic, basic, or neutral) after mixing metal oxide with water depends on the type of metal oxide. Some metal oxides, particularly those of alkali metals and alkaline earth metals (Group 1 and 2 in the Periodic Table), form basic solutions when dissolved in water. For instance, sodium oxide or magnesium oxide will react with water to form their respective hydroxides, which are basic in nature.
However, certain metal oxides like aluminum oxide or zinc oxide may react with water to form amphoteric solutions (can behave as both acids and bases).
Thus, not all metal oxides will make the water acidic when mixed.
