Calculate The Number of The Protons, Neutrons and Electrons.

1. 7·H₂O, with the following Compounds: ³H and ¹⁵O
2. 3·C₆H₁₂O₆, with the following Compounds: ²H, ¹⁶O, ¹³C

---

Lösung:

1. for each ³H: 1p, 1e^–, 2n, ¹⁵O: 8p, 8e^–, 7n
       1·H₂O This means that 10p, 10e^–, 11n
       7·H₂O: 70p, 70e^–, 77n
2. for each for each ¹³C: 6p, 6e^–, 7n … for each ²H: 1p, 1e^–, 1n, … for each ¹⁶O: 8p, 8e^–, 8n,
       1·C₆H₁₂O₆ This means that 6·6+12·1+6·8=96p, 96e^–, 6·7+12·1+6·8=102n
       3·C₆H₁₂O₆: 288p, 288e^–, 306n
