30 mLof0.1 M BaCl2is mixed with40 mLof0.2 MAl2SO43. What is the weight ofBaSO4formed ?BaCl2  +Al2SO43→ BaSO4 + AlCl3[Molecular Mass of BaSO4= 233]

Options:

Answer:
B
Solution:

First balance it 3 BaCl 2 + Al 2 SO 4 3 → 3 BaSO 4 + 2 AlCl 3 mM before reaction 3 0 × 0 . 1 4 0 × 0 . 2 = 3 = 8 0 0 mM after reaction 0 8 - 1 3 2

∵   3 mM of BaCl2reacts with one mole ofAl2SO43.

∴   mM of BaSO4 formed = 3 =wt.mol wt.×1000;

∴ wt. ofBaSO4formed=3 ×2331000= 0.699 g
