Question

Pure salt is made up of sodium and chloride. Each gram of salt contains 0.393 g of sodium. About how much sodium is in 59.8 g of pure salt?
A 24 g
B 1.3 g
© 43 g
D
13 g

Answer 1

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**
