Work Step by Step
This assignment can be solved with two simple proportions. For the first, we compare the sodium content in 100g of salt with the mass of salt that contains 2,4g of salt (the FDA recommendation).
Now, we use previously obtained value form a to determine the mass of snack that contains the previously calculated mass of the salt, by using the new proportion.
We rearrange to calculate the mass of snack that contains the calculated mass of salt. At the end, we round the solution to 3 significant figures.
