Question

The recommended daily intake of potassium (K) is 4.725 grams. The avergae raisin contains 3.677 mg K. Assuming that each raisin contains 3.677 milligrams, how many raisins per day would a person need to eat to meet the recommended daily amount of K from consuming raisins alone?

Answer 1

3.677mg =$0,003677g \ \ \ \ \ \ \ \ \Rightarrow \ \ \ \ \ \ \ 1 \ raisin\\ 4,725g \ \ \ \ \ \ \ \ \ \ \ \ \Rightarrow \ \ \ \ \ \ \ \ x\\\\ x=\frac{4,725g*1}{ 0,003677g}\approx 1285 \ raisins$

Answer 2

Answer: A person should consume 1285 raisins per day.

Explanation:

It is given that the total intake of potassium for a person is 4.725 grams and a contains an average of 3.677 mg of potassium in it.

We need to find the total number of raisins that a person must consume in order to have the daily intake of potassium.

For, this we require a conversion factor:

$1g=1000mg\\\\3.677mg=\frac{3.677}{1000}=0.003677g$

To calculate the number of raisins, we divide the total intake by the amount of potassium one raisin contain, we get:

$n\times 0.003677=4.725\\\\n=\frac{4.725}{0.003677}=1285$

Hence, a person should consume 1285 raisins per day.
