Calculate the number of gram atoms and gram molecules in 2.54 mg of iodine `(I_(2))` . (Atomic mass of I = 127 amu).

Explanation

To solve the problem of calculating the number of gram atoms and gram molecules in 2.54 mg of iodine (I₂), we will follow these steps:

### Step 1: Convert milligrams to grams
The mass of iodine is given as 2.54 mg. We need to convert this to grams, since the calculations require mass in grams.

\[ \text{Mass in grams} = 2.54 \, \text{mg} \times \frac{1 \, \text{g}}{1000 \, \text{mg}} = 0.00254 \, \text{g} \]
