The boiling point increase of a solution is a colligative property, which means that it is related with the solvent and the concentration of the solute, as per this formula:
ΔT = i * kb * m
Where, ΔT is the increase in the boiling point, i is the van't Hoof factor (which accounts for the numberof particles that are dissolved), kb is the boiling point and m the molality of the solution.
Gvien the normal boiling point of 100°C for pure water, ΔT = 101.4 °C - 100.0 °C = 1.4 °C.
Kb = 0.512 °C / m
m = 1.2 m
Therefore, i = ΔT / (kb * m) = 1.4°C / (0.512 °C/m * 1.2m) = 2.28
Answer: 2.28
The balanced equation for the combustion reaction is as follows
4C₂H₅ + 13O₂ --> 8CO₂ + 10H₂O
coefficients for the reactants and products are
C₂H₅ - 4
O₂ - 13
CO₂ - 8
H₂O - 10
Protons and neutrons and it is located in the nucleus
