Answer : The mass of sodium chloride present in 4.20 mole of NaCl are 245.7 grams.

Explanation : Given,

Moles of sodium chloride (NaCl) = 4.20 mole

Molar mass of sodium chloride (NaCl) = 58.5 g/mole

Formula used :

$\text{ Mass of }NaCl=\text{ Moles of }NaCl* \text{ Molar mass of }NaCl$

Now put all the given values in this formula, we get the mass of sodium chloride.

$\text{ Mass of }NaCl=(4.20moles)* (58.5g/mole)=245.7g$

Therefore, the mass of sodium chloride present in 4.20 mole of NaCl are 245.7 grams.
