Answer:
part (a) was used to calculate the molar mass of the metal M. In part (c) students proposed an experimental test that could be used to determine if MI 2 is an ionic solid, and then explained how the results of the test supported this claim. Students explained why I 2 is solid at room temperature, but Br 2 is a liquid in part (d). its {c}
Answer:
18.8 mL
Explanation:
The dilution formula states that the product between the initial molarity and the initial volume should be equal to the product between the final molarity and the final volume, since the number of moles of a substance remains constant in a dilution process:
We are given the initial molarity of the stock solution , the final molarity of the diluted solution and the final volume of the diluted solution .
Rearranging the expression for the volume of the stock solution, we get:
Therefore, 18.8 mL of the stock solution are required.
