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 :
[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 the mass of sodium chloride.
[tex]\text{ Mass of }NaCl=(4.20moles)\times (58.5g/mole)=245.7g[/tex]
Therefore, the mass of sodium chloride present in 4.20 mole of NaCl are 245.7 grams.
