Answer : The mass of sodium chloride obtained are 5.926 grams.

Explanation : Given,

Volume of solution = 350 mL

Molarity of sodium chloride = 0.287 M

Molar mass of sodium chloride (NaCl) = 59 g/mole

Molarity : It is defined as the number of moles of solute present in 1 liter of solution.

Formula used :

$\text{Molarity}=\frac{\text{Mass of sodium chloride}* 1000}{\text{Molar mass of sodium chloride}* \text{Volume of solution (in mL)}}$

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

$0.287M=\frac{\text{Mass of sodium chloride}* 1000}{59g/mole* 350mL}$

$\text{Mass of sodium chloride}=5.926g$

Therefore, the mass of sodium chloride obtained are 5.926 grams.
