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?

2.954grams of pottasium for that week

Explanation:

According to this question, a medium-sized that weighs 118grams contains 422 milligrams (mg) of potassium nutrient.

If someone eats a medium-sized banana each day for a week, this means that the person has consumed 422mg of pottasium that day.

Since there are 7days in a week, the person will consume 422 × 7 = 2954 mg of pottasium that week.

The question asks for the total pottasium intake in grams for that week, hence, we need to convert 2954 milligrams to grams.

1000mg = 1 g

Hence, 2954mg will be 2954/1000

= 2.954grams

Therefore, 2.954grams of pottasium are ingested by that person that week.

not clear

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
