El valor de la presión osmótica que corresponde a una solución que contiene 2 moles de soluto en un litro de solución a una temperatura de 17°C es 47.56 atmósferas.
La presión osmótica se puede calcular usando la siguiente ecuación:
(1)
En donde:
n: es el número de moles = 2 moles
R: es la constante de los gases = 0.082 L*atm/(K*mol)
T: es la temperatura = 17 °C = 290 K
V: es el volumen = 1 L
Introduciendo lo valores anteriores en la ecuación (1), tenemos:
Por lo tanto, la presión osmótica es 47.56 atmósferas.

Can you please explain what the BTB is so I may help ya?
The downside of this is that the longer lasting material is more difficult to break down.
Both natural fibers and synthetic fibers are polymer materials. Polymer materials are materials that are made by the agglomeration of small molecules called monomers.
The natural fibers are less long lasting than the synthetic fibers. The downside of this is that the longer lasting material is more difficult to break down. As a result of these, synthetic fibers lead to environmental pollution problems.

Answer:
Hi, the statements given in the question (a and b) are combination of right and wrong answers. But i will split the statement a and b into necessary fragments.
Carbohydrates are quick source of energy relatively. That is the only correct statement in the question.
Explanation:
Carbohydrates are naturally occurring organic compounds containing carbon, hydrogen and oxygen with the general formula (Cx H2y Oy) or Cx (H2O)y. They can be classified into simple sugar or complex sugar.
Simple sugars can be further divided into Monosaccharides (e.g glucose, fructose and galactose) and Disaccharides (e.g sucrose and maltose).
Complex sugar can be referred to as Polysaccharides (e.g cellulose and starch)
The statement above that says carbohydrate contains carbon, hydrogen and nitrogen polymers is not correct.
Carbohydrates are not mostly monosaccharides. They also contain Disaccharides and Polysaccharides.
They are not the only source of fuel.
Answer:
The correct answer is b polar covalent
Explanation:
When two atoms joined by covalent bond has difference in their electronegativities at that time polarity arise.
When the electronegativity difference is low such as 1.3 then the polar bond formed by the two atoms are called polar covalent bond.For example H2O
on the other hand polar bond formed by two atoms having high difference in their electronegativities is called ionic bond.For example NaCl.
