How many calories do 50 squats burn?

It's very difficult to determine how many calories are burned during any weight lifting activity because there are so many variables. It depends on how much you weigh, if you're using extra weight, how long it takes you to do 50 repetitions, and how long you rest between each rep. Also, weight lifting exercises like squats are not normally used to burn calories, because aerobic exercise is the best if you're concerned about how many calories you're burning.
