To solve this problem, we need to understand the relationship between the masses of boxes A and B and how they relate to the number of particles.Given:- Mass of box A = 10 grams- Mass of box B = 5 gramsWe assume that the number of particles is directly proportional to the mass. Therefore, if you have a certain mass of B, you can find the equivalent mass of A that contains the same number of particles by setting up a proportion.1. **As 7.5 grams of B:** Since 5 grams of B is equivalent to 10 grams of A (because one B is half the mass of one A), we set up the proportion:
Solving for
:
2. **As 2.5 grams of B:** Using the same method:
Solving for
:
3. **As 12.5 grams of B:** Again, using the proportion:
Solving for
:
4. **As 1 gram of B:** Finally, for 1 gram of B:
Solving for
:
Therefore, the answers are:- As 7.5 grams of B: 15 grams of A- As 2.5 grams of B: 5 grams of A- As 12.5 grams of B: 25 grams of A- As 1 gram of B: 2 grams of A
