Paso 1: Ordenar los datos. Soluto urea : masa molar = 60 g/mol Solvente agua : Tºeb = 100 °C masa molar = 18 g/mol Keb = 0,52 °C/molal Solución : concentración = 20 % p/p masa = 100 g

Paso 2: Pregunta concreta ⇒determinar el punto de ebullición de la solución (Teb). Paso 3: Aplicamos las ecuaciones:

Explanation:

¿Cuál es el punto cuál es el pùnto de ebullición de 100g de una solución acuosa de urea al 20% m/m, si la masa molar de urea de ebullición de la solución resultante

Answer from: Quest

If the water vapor content stays the same and the temperature drops, then the relative humidity increases. its vise versa.if the water vapor content stats the same and the temperature rises, the relative humidity decreases. so, yes, i'd say that temperature and humidity have a strong relationship.

Answer from: Quest

he uptake of drugs from the intestine is often strongly influenced by diffusion. for example, consider a water-insoluble steroid for treating inflammation that is solubilized in aggregates of detergent molecules, called micelles. these micelles, aggregates of 80 soap molecules, have a molecular weight of 24,000, a diameter of 2.6 nm, and a charge of -27. the positively charge ions (counterions) in this system are na".

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.
