Place these foods in order of their vitamin C content, from highest to lowest.
castortr0y [4]

Answer:

½ c raw red bell pepper  (190 mg per cup)

1 medium orange  (96 mg per cup)

½ cup cooked broccoli (81 mg per cup, uncooked)

¾ cup tomato juice  (44 mg per cup, 33 mg in 3/4 cup)

Explanation:

Even if the reference measurements is 1 cup the proportion of vitamin C is maintained when half a cup of the measure is used.

As I do not know the size of the orange I am considering that half an orange is equal to half a cup.

Brococoli is cooked and Vitamin C is vulnerable to the cooking process and breaks down easily. So its vitamin C content will vary depending on how it was cooked and how long it lasted.
