Answer :
Final answer:
To determine how many grams of potassium are in 12.25 kg of apples, you need to first convert the weight to pounds, then determine the number of apples, and multiply that by the amount of potassium per apple. The final result is approximately 12.88g of potassium.
Explanation:
To begin with, we should first convert the mass of the apples from kilograms to pounds, since we know the amount of potassium in an apple in terms of pounds. To do this, we use the following conversion rate: 1 kg = 2.20462 lbs. So, for 12.25 kg of apples, we have approximately 27 lbs. of apples.
As there are about 3 apples in a pound, we then multiply this weight by 3 to obtain the approximate total number of apples, which is around 81 apples.
Finally, since each apple contains 159 mg of potassium, the number of total apples is multiplied by the amount of potassium per apple to obtain the total amount of potassium in milligrams. The total potassium amount in this case is 81 x 159 mg, equals approximately 12879 mg.
As we need to calculate this amount in grams, we perform a simple conversion: 1000 mg equals 1 g. Therefore, 12879mg equals roughly 12.88g of potassium.
