Tomatoes are pretty heavy. Chopped finely and it would be about two cups. Cups is a measure of volume. Pounds is a measure of weight and mass. You can not directly convert the two.
Foods that are being chopped include carrots, celery, tomatoes, onions, and more. There are tons of foods that can be chopped, and often should be before they are eaten.
Stewed tomatoes are just tomatoes cooked with other vegetables of your choice. Onions, celery, bell pepper and herbs or spices you like. There is no one recipe for them. Just peel and chop the tomatoes and add some onion, celery, etc. and simmer until everything is tender. Season to your taste.
That is approximately 0.368 cup.
You can freeze tomatoes in any form, the only effect freezing has on tomatoes is that they will soften when defrosted, similar to canned tomatoes.
