A compound contains 50% Ca, 15% C and 35% N atoms by mass. Determine the simplest formula of the compound. (R.A.M.: C = 12, N = 14, Ca = 40.)

Explanation

To determine the simplest (empirical) formula of the compound containing 50% Calcium (Ca), 15% Carbon (C), and 35% Nitrogen (N) by mass, we can follow these steps:

### Step 1: Assume a 100 g Sample
Assuming we have a 100 g sample of the compound makes calculations straightforward.

- Mass of Calcium (Ca) = 50 g
- Mass of Carbon (C) = 15 g
- Mass of Nitrogen (N) = 35 g
