Answer:the mass of the air inside the inflated balloon is 4 grams
Step-by-step explanation:
The initial mass of the balloon before it was inflated by the Math and Science class is 4 grams. After the balloon was inflated, the mass was 8 grams. This means that the mass by which the balloon increased would be the mass of the inflated balloon - the initial mass of the balloon. It becomes
8 - 4 = 4 grams.
Therefore, the mass of the air inside the inflated balloon is 4 grams.
