For every one can of Campbell's tomato soup there are around 2 servings per can.
But sometimes one can of Campbell's tomato soup may only be one serving depending on how much of the soup the person is gonna eat.
I can eat one can of Campbell's tomato soup myself so for me it would be one serving because it's so good.
But you can feed 2 people especially 2 kids with one can of Campbell's tomato soup along with feeding the kids some other food.
