Calculate the density of the four solutions. All of the solutions has the volume equal to 25 ml. Red solution has 25.0 g of mass
Scilla [17]

Answer:

              B. Green solution density is 1.06 g/ml and blue solution density is 1.20 g/ml

Explanation:

Density is given as,

                               D = Mass / Volume

Red Solution,

                               D = 25 g / 25 mL

                               D = 1 g/mL

Green Solution,

                               D = 26.5 g / 25 mL

                               D = 1.06 g/mL

Yellow Solution,

                               D = 28.2 g / 25 mL

                               D = 1.128 g/mL

Blue Solution,

                               D = 30 g / 25 mL

                               D = 1.20 g/mL

The most likely van't Hoff factor for an 0.01 m calcium iodide solution is
monitta

This problem is providing us with the molality of a solution of calcium iodide as 0.01 m. So the most likely van't Hoff factor is required and theoretically found to be 3 due to the following:

<h3>Van't Hoff factor:</h3>

In chemistry, the correct characterization of solutions also imply the identification of the ions it will release in aqueous solution. For that reason, the van't Hoff factor gives us an idea of this number, according to the formula the solute has got.

In such a way, for calcium iodide, we write its ionization equation as shown below:

CaI_2\rightarrow Ca^{2+}+2I^-

Assuming it is able to ionize due to the low molality, because if it was higher, then it won't ionize. Hence, since we have three moles of ion products, one Ca²⁺ and two I⁻, we can conclude the van't Hoff factor would be 3, although calculations may lead to a different, yet close result.
