Answer : The mass of sodium chloride (NaCl) are 257.4 grams.

Explanation : Given,

Moles of sodium chloride (NaCl) = 4.40 mole

Molar mass of sodium chloride = 58.5 g/mole

Formula used :

[tex]\text{Mass of }NaCl=\text{Moles of }NaCl\times \text{Molar mass of }NaCl[/tex]

Now put all the given values in this formula, we get:

[tex]\text{Mass of }NaCl=4.40mole\times 58.5g/mole=257.4g[/tex]

Therefore, the mass of sodium chloride (NaCl) are 257.4 grams.
