It was great! Jane brought bubble gum to school and it was so good!
Bubble gum! That has a LOT of sugar! I hope you didn't eat too much.
It doesn't have that much sugar, and I only had one pack anyways.
Annie, that is actually a lot of sugar! I'll show you exactly how much. Lets perform an experiment!
Okay Annie, we need to calculate the mass of sugar in one piece of gum. To do this, we need the mass of one piece of fresh gum, which is 8.19 grams. I got this number because the mass of the gum and the wrapper, 8.37 g, subtracted by the mass of the wrapper, 0.18g, is 8.19g. We also need the mass of chewed gum, so please chew on this piece!
Okay, I'm almost done!
Alright, now that you are done, we can calculate the mass. First, we need the mass of the wrapper, which is 0.18 grams. Next, we need the mass of the chewed gum and paper, which is 2.84 grams. Then, to get the mass of the chewed gum, we just need to subtract.
Oh! 2.84g - 0.18g = 2.66g, so the mass of chewed gum is 2.66g!
So, the mass of sugar is equal to the mass of fresh gum subtracted by the mass of chewed gum, which is 8.19g - 2.66g = 5.53g.
So the mass of sugar in one piece of gum is 5.53 grams! I wonder what percent that is?
