The average weight of a grade "A" large chicken egg is 57 grams /2.01 oz.
therefore three eggs would weight 171 grams or 6.03 oz.
You would need three eggs for three egg whites. The whites of the eggs must be separated from the yolks.
Almost half
You would use 4 medium egg whites or 5 small egg whites.
It is very difficult to answer this question seriously. The abbreviation for ounces is "oz". It is only if I assume that you did not know this fact, that the question has any validity.3
The total calories are:approx 48-51 calories in 3 egg whites.

Yes, you do use egg whites
6 medium egg whites equal 3 whole eggs
one egg white = 3 tablespoons (T) egg substitute 15 ml = 1 T 3 T = 45 ml 8 oz = 240 ml 240 / 45 = 5.333... egg whites in an 8 oz carton of egg substitute
A box cake calling for 3 egg whites would not rise properly without the egg whites. Applesauce is not a suitable substitute for egg whites. Possible solutions would be to borrow eggs from a neighbor, or prepare a different dessert using available ingredients.
3 egg whites have about 45-50 calories, and 1 piece of toast contains roughly 70 calories. So all together, that would be somewhere between 115-120 calories.
Well if you use just the egg whites and use light mayo (2 Table spoons) and mustered it will be about 3 points. :)
