110 calories are required to raise the temperature.
-
Specific heat = calories / mass * (final temperature - initial temperature)
Insert known factors of the equation before rearranging to isolate the unknown (in this case, calories)
0.11 = calories / 10 * (200 - 100)
0.11 = calories / 10 * 100
0.11 * (10 * 100) = calories
0.11 * 1000 = calories
110 = calories
yes

Answer: The molality of solution is 0.66 mole/kg
Explanation:
Molality of a solution is defined as the number of moles of solute dissolved per kg of the solvent.
where,
n = moles of solute
= weight of solvent in g
moles of 
= 
Now put all the given values in the formula of molality, we get
Therefore, the molality of solution is 0.66 mole/kg
The answer is: both choices a and b.
The base SI unit for molar mass is kg/mol, but chemist more use g/mol (gram per mole).
For example, the molar mass of fluorine is 38.00 g/mol.
M(F₂) = 2 · Ar(F) · g/mol.
M(F₂) = 2 · 19.00 · g/mol.
M(F₂) = 38.00 g/mol.
Molar mass M represent the mass of a substance (in this example molecule of florine) divided by the amount of substance.
Ar is the atomic weight of a chemical element (in this example fluorine).
