Answer:
The answer to your question is m = 3.2
Explanation:
Molality is defined as the number of moles of a solute dissolved in a mass of solvent (kg).
Data
moles of solute = 43.6
mass of solvent = 13.5 kg
Formula
Molality = 
Substitution
Molality = 
Simplification and result
Molality = 3.2
An atom is the smallest particle of an element that retains the chemical properties of the element. Atoms are electrically neutral, with a positively charged nucleus that binds one or more electrons in motion around it.
An ion-An atom or molecule that has acquired a charge by either gaining or losing electrons. An atom or molecule with missing electrons has a net positive charge and is called a cation*; one with extra electrons has a net negative charge and is called an anion*.

½H2(g) + ½I2(g) → HI(g) ΔH = +6.2 kcal/mol
or...
½H2(g) + ½I2(g) + 6,2kcal/mole → HI(g)
________
21.0 kcal/mole + C(s) + 2S(s) → CS2(l)
or...
