Nutritional tables give the potassium content of a standard apple (about 3 apples per pound) as 159 mg. How many grams of potassium are in 3.25 kg of apples?

Answer :

Final answer:

To find the amount of potassium in 3.25 kg of apples, we can set up a proportion using the potassium content of a standard apple. Using cross-multiplication, we find that there are approximately 171.65 grams of potassium in 3.25 kg of apples.

Explanation:

To find the amount of potassium in 3.25 kg of apples, we need to first convert 3.25 kg to grams. There are 1000 grams in 1 kilogram, so 3.25 kg is equal to 3.25 * 1000 = 3250 grams. Next, we can set up a proportion using the information given in the nutritional table:

3 apples (159 mg) = x grams (potassium content)

We can cross-multiply and solve for x:

3 * x = 159 * 3250

x = 159 * 3250 / 3

x ≈ 171,650 mg ≈ 171.65 grams

Therefore, there are approximately 171.65 grams of potassium in 3.25 kg of apples.
