Answer:

1. The volume of solution A (1.31%) will decrease.

2. The volume of solution D (11.7%) will increase.

Explanation:

1. If two solutions are separated by a semipermeable membrane, the water molecules will move through the membrane starting from the solution that has the low concentration of the solute towards the solution that has a high concentration of the solute. Therefore, if solution A has 1.31% starch and solution B has 7.48% starch, it can be seen that solution B has a higher concentration. This is why the water molecules will move from Solution A to Solution B.

2. Like exercise 1, solution C has a concentration of 6.75% NaCl and solution D has a concentration of 11.7% NaCl. Therefore, with solution D having a higher concentration, the water molecules will move from solution to solution D.

An object has a mass of 441 g and a volume
Ratling [72]

Answer:

<h3>The answer is 4.41 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume}  \\

From the question we have

density =  \frac{441}{10}  \\

We have the final answer as

<h3>4.41 g/cm³</h3>

Hope this helps you

If starch, glucose and NaCl are soaked in the dialysis tubing , will there be a difference between the beginning and after 15min
spin [16.1K]
<span>Yes. If you put solutions containing the same concentration table salt, glucose and starch in different bags and place the bags in water (i.e., 0M) solution, then the bag with salt will contain more water after 15 minutes than the bag with glucose, which will contain more than the bag with starch.</span>
