Sog‘lom odamning qon plazmasi tarkibidagi Na⁺, K⁺, Ca²⁺ ionlarining mol nisbati doimiy ravishda 1 : 1,4 : 9,6 bo‘ladi. Agar plazmadagi Na⁺ ionining massasi 11,5 g bo‘lsa, ionlarning miqdorlarini (mol) mos ravishda aniqlang.

  1. 0,5; 0,7; 7,5
  2. 0,5; 1,32; 4,8
  3. 0,9; 0,7; 4,8
  4. 0,5; 0,7; 4,8

📝 Detailed explanation

Eslatma: nisbat aslida 1 : 1,4 : 9,6 bo‘lsa ham, masalada Ca²⁺ ulushi 9,6 emas, 9,6/10 sifatida ishlatiladi. n(Na⁺) = 11,5/23 = 0,5 mol. K⁺ = 0,5·1,4 = 0,7 mol. Ca²⁺ = 0,5·9,6 = 4,8 mol.
