Describe how you would prepare 500ml of 40% (w/v) aqueous iodine solution. [Atomic mass of iodine =127g/mol].

- Weight 333.3 grams of iodine.

- Measure 500 mL of water.

- Vigorously mix the resulting solution.

Explanation:

Hello,

In this case, since 500 mL of a 40% (w/v) aqueous solution iodine is required, we can compute the required mass of iodine by defining the given mass-volume percent:

In such a way, we need to find mass of iodine, which is computed as:

Thereby, the procedure will be:

- Weight 333.3 grams of iodine.

- Measure 500 mL of water.

- Vigorously mix the resulting solution.

Best regards.

a electronegativity decreases beacuse the size of nucleus is bigger.
