The hormone thyroxine is secreted by the thyroid gland and has the formula: c15h17no4i4. how many milligrams of iodine can be extracted from 15.0 grams of thryoxine?

Answer : The mass of iodine extracted can be 9796.7 mg

Explanation : Given,

Mass of thryoxine = 15.0 g

Molar mass of thryoxine = 776.86 g/mole

The molecular formula of thryoxine is,

In compound, there are 15 moles of carbon, 11 moles of hydrogen, 1 mole of nitrogen, 4 moles of oxygen and 4 moles of iodine.

First we have to determine the moles of thryoxine.

Now we have to determine the moles of iodine.

As, 1 mole of thryoxine has 4 moles of iodine

So, 0.0193 mole of thryoxine has moles of iodine

Now we have to determine the mass of iodine.

conversion used : (1 g = 1000 mg)

Therefore, the mass of iodine extracted can be 9796.7 mg
