Question

sodium iodie formula and molar mass

Answer 1

The chemical formula for sodium iodide is NaI.

To calculate the molar mass of sodium iodide (NaI), you can add the molar masses of sodium (Na) and iodine (I):

- Sodium (Na): approximately 22.99 g/mol
- Iodine (I): approximately 126.90 g/mol

Now, add the two values together:

\[
\text{Molar mass of NaI} = \text{Molar mass of Na} + \text{Molar mass of I} = 22.99 \, \text{g/mol} + 126.90 \, \text{g/mol} \approx 149.89 \, \text{g/mol}
\]

So, the molar mass of sodium iodide (NaI) is approximately **149.89 g/mol**.
