Kaliy, kalsiy va xrom (III) oksidlaridan iborat 18,1 g aralashma sulfat kislota bilan to‘liq ta’sirlashganda 26,1 g metall sulfatlari aralashmasi hosil bo‘ldi. Jarayonda sarflangan sulfat kislotaning miqdorini (mol) hisoblang.

  1. 0,1
  2. 0,15
  3. 0,2
  4. 0,05

📝 Detailed explanation

Massa ortishi: Δm = 26,1 − 18,1 = 8 g, bu O²⁻ ning SO₄²⁻ ga almashishi natijasi: har bir mol H₂SO₄ uchun massa 96 − 16 = 80 g ortadi. n(H₂SO₄) = 8/80 = 0,1 mol.
