To find out how much sodium is in 59.8 g of pure salt, we can use the proportion of sodium in one gram of salt.

Given that each gram of salt contains 0.393 g of sodium, we can calculate the amount of sodium in 59.8 g of salt:

\[ \text{Amount of sodium} = \text{mass of salt} \times \frac{\text{mass of sodium}}{\text{mass of salt}} \]

\[ \text{Amount of sodium} = 59.8 , \text{g} \times 0.393 , \text{g sodium/g salt} \]

Calculating that:

\[ \text{Amount of sodium} = 59.8 \times 0.393 \approx 23.5 , \text{g} \]

Since we want to match this to the closest answer, we see that the correct approximate value is roughly 24 g.

Therefore, the answer is:

A 24 g
