A medium-sized banana (118g) on average contains 422 mg of potassium - a nutrient needed to maintain fluid balance. If someone eats a medium-sized banana each day for a week, how many total grams of potassium are ingested in that week?

Respuesta :

Answer:

2.954 g

Explanation:

One banana contains 422 mg

One banana weighs 118 g

To make our calculations easier, we will convert both unit to the same power, that is both of them will be in g.

422 mg = 422/1000 = 0.422 g

If one banana contains 0.422 g of potassium, then 7 bananas(since he eats 1 per day) will weigh

0.422 * 7 = 2.954 g

Thus, after a week, he would have ingested at least 2.954 g of potassium.

I hope you understand the explanations. Thanks
