The three elements A, B and C form three compounds AB, AC and BC. AB contains 75% of A, AC contains 57.14% of C while BC contains 11.11% of B. Prove that these results are in accordance to law of reciprocal proportions.

Explanation

To prove that the results are in accordance with the law of reciprocal proportions, we will follow these steps:

### Step 1: Determine the Masses of Elements in Each Compound

1. **For Compound AB**:
- Given that AB contains 75% of A, we can deduce that:
- Mass of A = 75 g
- Mass of B = 100 g - 75 g = 25 g
