To find the molar mass of iodine (I), you can refer to the periodic table. The molar mass is essentially the mass of one mole of iodine atoms, usually expressed in grams per mole (g/mol).
The molar mass of iodine is approximately 126.90 g/mol. This value is derived from the atomic weight listed on the periodic table, which is based on the weighted average of all naturally occurring isotopes of iodine. Therefore, if you want to calculate the molar mass of iodine for use in chemical equations or calculations, you would use this value.
For practical purposes, you can simply look up iodine on the periodic table. Iodine is located in group 17 (halogens) and Period 5. The atomic mass indicated there provides you with the accurate molar mass you need for your calculations.
