В смеси, состоящей из 0,5 моль HClO и HClO₂, число химических связей равно 1,6·N_A. Определите массу смеси.

  1. 20,55
  2. 42
  3. 31,05
  4. 45

📝 Detailed explanation

Пусть x моль HClO (σ=2) и y моль HClO₂ (σ=4): x+y=0,5; 2x+4y=1,6 → y=0,3; x=0,2. m = 0,2·52,5 + 0,3·68,5 = 10,5 + 20,55 = 31,05 г.
