One hundred grams of broccoli florets is approximately equal to 1 to 1.5 cups, depending on how tightly they are packed. Generally, 1 cup of chopped broccoli weighs about 91 grams, so this can vary slightly based on the size and cut of the florets.
5 broccoli florets is equal to 1/2 a cup. So that means that 20 broccoli florets is equal to 2 cups.

Broccoli
The entire plant is broccoli. The part you like to eat is 'florets'
You could say that the florets are healthier than the stems. Broccoli is high in minerals and vitamins such as beta carotene, calcium, iron, thiamin, riboflavin, niacin, and vitamin C. But there is more beta carotene in the florets than there is in the rest of the plant. And the darker the green color of the florets, the higher the beta carotene and vitamin C content. Although raw broccoli is healthy, cooking releases more of the nutrients.
BROCCOLI : a green vegetable with edible leaves and "flower" heads (florets).
If you look closely at a head of broccoli you will find smaller stems that resemble the full sized broccoli head. http://www.istockphoto.com/file_thumbview_approve/4265787/2/istockphoto_4265787-two-broccoli-florets.jpg
Chinese broccoli is a more leafy vegetable with less (or none) of the florets that we generally consider characteristic of "regular" broccoli.
To freeze broccoli and cauliflower effectively, start by washing and cutting them into small florets. Blanch the florets in boiling water for a few minutes, then quickly cool them in ice water. Drain the florets thoroughly and place them in airtight containers or freezer bags. Label the containers with the date and store them in the freezer for up to 12 months.
