Answer : The number of servings of this potato chips eaten to consume 0.0230 moles of NaCl must be, 5.39

Explanation :

First we have to calculate the moles of NaCl.

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

$\text{Moles of NaCl}=\frac{250.0mg}{58.55g/mol}=\frac{0.250g}{58.55g/mol}=0.004269mol$

Now we have to calculate the number of servings.

As, the number of serving in 0.004269 moles of NaCl = 1 serving

So, the number of serving in 0.0230 moles of NaCl = $\frac{0.0230}{0.004269}=5.39$ serving

Thus, the number of servings of this potato chips eaten to consume 0.0230 moles of NaCl must be, 5.39
