The question is in an image. You need to use "CER" which is in one of the images and the reference table G which is in another of the images. "CER" means 3 words: Claim (The answer), Evidence (Why the answer is right) and Reasoning (Connect answer to evidence).

Answer:

C: Claim the answer.

No, 100 g of NH4Cl will not form a saturated solution with 200 g of water.

E: Evidence.

According to table G and by doing a rule of three, we obtained 124 g of NH4Cl and the question is asking if a solution with 100 g of NH4Cl with 200 g of water.

R: Reasoning.

According to the result that we obtained from the rule of three, we need 124 g of NH4Cl to form a saturated solution with 200 g of water, so 100 g of NH4Cl with 200 g of water will form an unsaturated solution.

Step-by-step explanation:

First, let's review the concept of a saturated solution: A saturated solution is a solution that contains the maximum amount of solute that is capable of dissolving.

You can see in the graph that at 70 °C, we can dissolve approximately 62 g of NH4Cl in 100 g of water to form a saturated solution. But, we want to confirm if 100 g of NH4Cl can be dissolved in 200 g of water to form a saturated solution, so let's state a rule of three:


\begin{gathered} 62\text{ g NH}_4Cl\rightarrow100\text{ g water} \\ x\text{ g NH}_4Cl\rightarrow200\text{ g water} \end{gathered}

The calculation of this rule of three would be:


62\text{ g NH}_4Cl\cdot\frac{200\text{ g water}}{100\text{ g water}}=124\text{ g NH}_4Cl.

To form a saturated solution of NH4Cl with 200 g of water, we will need 124 g of NH4Cl. As we obtained 124 g of NH4Cl and the question is asking if a solution with 100 g of NH4Cl with 200 g of water will form a saturated solution would be wrong because this amount doesn't reach the maximum of solute. This would be an unsaturated solution (an unsaturated solution is a solution that contains less than the maximum amount of solute that is capable of being dissolved).

C: Claim the answer.

No, 100 g of NH4Cl will not form a saturated solution with 200 g of water.

E: Evidence.

According to table G and by doing a rule of three, we obtained 124 g of NH4Cl and the question is asking if a solution with 100 g of NH4Cl with 200 g of water.

R: Reasoning.

According to the result that we obtained from the rule of three, we need 124 g of NH4Cl to form a saturated solution with 200 g of water, so 100 g of NH4Cl with 200 g of water will form an unsaturated solution.
