Answer: M = 0.01 M C12H22O16
Explanation: First convert the mass of C12H22O16 into moles using the molar mass of the compound.
5 g C12H22O16 x 1 mole C12H22O16 / 342 g C12H22O16
= 0.01 mole C12H22O16
To calculate the molarity we will use the following formula.
M = n / L
= 0.01 mole / 1 L
= 0.01 M C12H22O16

Answer:
The freezing point depression can be calculated using the pure solvent freezing point and the molality of the solution.
At the freezing point, the vapor pressure of both the solid and liquid form of a compound must be equal.
The freezing point of a substance is the temperature at which the solid and liquid forms are in equilibrium.
To reattain equilibrium, the freezing point of the solute and solvent mixture is lowered relative to the original pure solvent.
Explanation: The atomic mass of iron (Fe) is 55.85 amu. The atomic mass of radium (Ra) is 226 amu. One mole of atoms of any element contains 6.022 X 1023 atoms, regardless of the type of element. The mass of one mole of an element depends on what that element is, and is equal to the atom mass of that element in grams.
The magnesium oxide is MgO. The mass percent of oxygen is 16/(24.3+16)=39.7%. For the given reaction, in my opinion, there will be magnesium left after reaction. <span />
