a student needs 0.015mol of iodine crystals (I2) , for an experiment what mass of iodine crystals should the student obtain?

Answer 1

The molar mass of iodine (I2) is 253.8 g/mol.

0.015 mol of iodine crystals = 0.015 mol x 253.8 g/mol

= 3.807 g of iodine crystals.

Therefore, the student should obtain 3.807 g of iodine crystals for the experiment.
