Panic!

Among the staples in my kitchen is Cool Whip. Everyone knows you can't make a dessert without it. I went to the store today and Cool Whip is sold in 1 liter containers! My recipes say "1 container" or "1/2 container!" Panic!

I looked up a recipe and a container should have 8 oz in it. But, obviously if it is 8 oz of volume then that's just 1 cup. No way, so it must be by weight. The question now is, what's the density of Cool Whip?

*Update*
With a little searching, I was able to find that an 8 oz tub has 3 or 3.25 cups in it. The Kraft website cannot agree with itself. But I think there are actually 3.25 cups. Therefore, my container has 4.41 cups in it, or 10.86 oz. Thanks to Cheryl for helping solve this crisis!

*Another Update*
The container says "yields 5 1/2 cups." I'm not sure how that is possible. It seemed to me as I measured it for a pie that it was much closer to the 4.41 cups than 5.5.
