प्रश्न
A box contains some identical red coloured balls, labelled as A, each weighing 2 grams. Another box contains identical blue coloured balls, labelled as B, each weighing 5 grams. Consider the combinations AB, AB2, A2B and A2B3 and show that law of multiple proportions is applicable.
उत्तर
| Combination of A and B | AB | AB2 | A, B | A2B3 |
| Mass of A (in g) | 2 | 2 | 4 | 4 |
| Mass of B (in g) | 5 | 10 | 5 | 15 |
Masses of B which combine with a fixed mass of A are
10 g, 20 g, 5 g, 15 g
2 : 4 : 1 : 3
This is the simple whole-number ratio.
