Answer is: molar mass of sodium iodide is 149.89424 g/mol.

Chemical reaction: Na⁺ + I⁻ → NaI.
The molar mass (M)<span> is the </span>mass<span> of a given substance (in this example sodium iodide</span><span>) divided by the </span>amount of substance<span>.
</span>M(NaI) = Ar(Na) + Ar(I) · g/mol.
M(NaI) = 22.98977 + 126.90447 · g/mol.
M(NaI) = 149.89424 g/mol.

kirill115 [55]

Answer:

Answer is attached but read below for full explanation.

Explanation:

This reaction is called Hydrolysis of Amides. Amides are carboxylic acid derivatives where the -OH of the carboxylic acid has been replaced by -NH2, -NHR, or -NR2 of an amine. Since the reaction between a carboxylic acid and an amine to give an amide also liberates water, this is an example of a "condensation reaction".
