How many moles of iodine should be added to 750 grams of carbon tetrachloride to prepare a 0.24 m solution

0.18 mol

Explanation:

Given data

Step 1: Convert the mass of the solvent to kilograms

We will use the relationship 1 kg = 1,000 g.

Step 2: Calculate the moles of the solute

The molality is equal to the moles of solute divided by the kilograms of solvent. Then,

Explanation:

Hello,

In this case, we considering the iodine as the solute and the carbon tetrachloride as the solvent, then for the given molal solution which is measured in moles of solute per kilograms of solvent we first compute the required kilograms:

Then, we can compute the moles:

Best regards.

c is the answer because when something is left after something evaporates that shows the chemical change.
