The patient can take 58.7904 ml of juice daily

Step-by-step explanation:

There is 500 mg of potassium in 1 cup (240 ml) of orange juice. The amount of potassium found in 240 ml of orange juice is 500 mg.

Let us convert the patient body weight to kg.

1 kg = 2.20462 Ib

? kg = 135 Ib

cross multiply

135/2.20462 = 61.2350427738 ≈ 61.24 kg

The patient weight in kg is 61.24.

The patient limits is 2 mg per kg of body weight per day from fruit juice. The patient limits with a weight of 61.24 kg will be 61.24 * 2 = 122.48 mg of potassium.

500 mg of potassium is in 240 ml of orange juice.

122.48 mg of potassium is? of ml of orange juice

cross multiply

ml of orange juice = (122.48 * 240) / 500

ml of orange juice = 29395.2 / 500

ml of orange juice = 58.7904 ml

The patient can take 58.7904 ml of juice daily
