a student needs 0.015mol of iodine crystals , for an experiment what mass of iodine crystals should the student obtain?

1 answer

The molar mass of iodine is 126.9 g/mol.

So, to find the mass of 0.015 mol of iodine crystals, we can use the following formula:

mass = moles x molar mass

mass = 0.015 mol x 126.9 g/mol

mass = 1.904 g

Therefore, the student should obtain 1.904 g of iodine crystals for their experiment.
