Answer:
Molality of the methanol solution = 8.33 m
Explanation:
Given:
Mass % = 21.1 %
Molar mass of methanol = 32.04 g / mol
Find:
Molality of the methanol solution?
Computation:
Moles of methanol = Mass / Molar mass
Moles of methanol = = 21.1 / 32.04
Moles of methanol = 0.658
Assume.
Mass of solution = 100 g
Mass of solvent = 100 -21.1 = 78.9 g = 0.0789 kg
Molality of the methanol solution = 0.658 / 0.0789
Molality of the methanol solution = 8.33 m
Answer:
The actual ∆H would be greater than the calculated value of ∆H with no calorimeter.
Explanation:
The amount of heat changed during this process at a fixed pressure is termed Enthalpy
enthalpy change ∆H = ∆E + P∆V
∆E = internal energy change
P = fixed pressure
∆V = change in volume
When energy is absorbed during reaction, it is called endothermic reaction.
Endothermic reaction carried out in the calorimeter and enthalpy change for the reaction. Since we have that
q(surrounding) = q(solution)+q(calorimeter)
Therefore, q(calorimeter) > 0(endothermic).
The actual ∆H would be greater than the calculated value of ∆H with no calorimeter.
