Answer:
-1.71 J/K
Explanation:
To solve this problem we use the formula
ΔS = n*ΔH/T
Where n is mol, ΔH is enthalpy and T is temperature.
ΔH and T are already given by the problem, so now we calculate n:
Molar Mass C₂H₅OH = 46 g/mol
2.71 g C₂H₅OH ÷ 46g/mol = 0.0589 mol
Now we calculate ΔS:
ΔS = 0.0589 mol * −4600 J/mol / 158.7 K
ΔS = -1.71 J/K
Answer:
the answer is
0.1342 mL

En una solución acuosa donde el agua es el solvente, el soluto que será disuelto por el agua tiene menos partículas, lo que hace que las partículas se muevan en un movimiento aleatorio. El agua pura tiene una baja concentración de iones y, por lo tanto, no conduce electricidad.
