Para determinar la presión osmótica de esta solución, primero necesitaremos calcular la concentración de la solución en términos de moles por litro. Luego, utilizaremos la fórmula de la presión osmótica para obtener el resultado final.

Paso 1: Calcular los moles de hidróxido de aluminio (Al(OH)3)
Para esto, necesitamos convertir los gramos de Al(OH)3 a moles. Utilizaremos la masa molar del compuesto, que es de 78 g/mol.

\text{Moles de Al(OH)3} = \frac{{534 \, \text{g}}}{{78 \, \text{g/mol}}} = 6.846 \, \text{mol}

Paso 2: Calcular el volumen en litros
Dado que el volumen de la solución se da en mililitros, necesitamos convertirlo a litros. Utilizaremos la relación de conversión 1L = 1000 ml.

\text{Volumen (litros)} = \frac{{2784 \, \text{ml}}}{{1000 \, \text{ml/L}}} = 2.784 \, \text{L}

Paso 3: Calcular la concentración en moles por litro
Utilizando los moles de Al(OH)3 y el volumen en litros, podemos calcular la concentración de la solución.

\text{Concentración (M)} = \frac{{6.846 \, \text{mol}}}{{2.784 \, \text{L}}} = 2.459 \, \text{M}

Paso 4: Calcular la presión osmótica
La fórmula para calcular la presión osmótica es:

\text{Presión osmótica} = \text{Concentración (M)} \times \text{R} \times \text{Temperatura (K)}

Donde R es la constante de los gases ideales, que tiene un valor de 0.0821 L·atm/(mol·K). Necesitamos primero convertir la temperatura a kelvin. Utilizando la fórmula:

\text{Temperatura (K)} = \text{Temperatura (°C)} + 273.15

\text{Temperatura (K)} = 91°C + 273.15 = 364.15 \, \text{K}

Sustituyendo los valores conocidos en la fórmula de la presión osmótica:

\text{Presión osmótica} = 2.459 \, \text{M} \times 0.0821 \, \text{L·atm/(mol·K)} \times 364.15 \, \text{K}

\text{Presi^^f3n osm^^f3tica}=73.52\,\text{atm}

Respuesta: La presión osmótica de la solución es de 73.52 atm.

Your boss asks you to plan the sample size for a randomized, double-blind, controlled trial in the clinical development of a cure for irritable bowl disease. Current standard treatment shall be compared with a new treatment in this trial. The S3-guideline of AWM demonstrated a mean change of the summary score of the validated health related quality of life questionnaire at 8 weeks of 16 with standard deviation 23 under standard treatment. You quote the drop-out rate of 11% from literature (previous phase of clinical development). Your research yielded a clinically important effect of 4 that has been found to be the Minimal Clinically Important Difference (MCID). In order to demonstrate superiority of the new treatment over standard of care, you assume that the change in of the summary score of the validated health related quality of life questionnaire follows a normal distribution, and that the standard deviation is the same for both treatments. How many patientes would one need to recruit for the trial to demonstrate the clinically interesting difference between treatments at significance level 5% with 95% power?
