Problem solved!!! (I love when I can actually help people on this site - I feel useful haha)
Fresh Mozzarella has 87 calories per ounce, and it is 24% fat (as well as 51% water, 20% protein, 4% carbohydrate, and 2% ash). Note it has a lot more water than packaged mozzerella, which is a good thing (and it tastes yummier...) but it also has more fat (also makes it taste way yummier!!!). 24% fat equals out to be about 6.75 grams. The good news is, it's an ok source of protein (5.5 grams) and a great source of calcium (146 mg). Each of your little balls is probably equal to about an oz of cheese, but without seeing the size it's hard to say.
