CH3COOH + NaHCO3 => CH3COONa + CO2 + H2O
mCH3COOH = 150 x 6/100 = 9 (g)
==> nCH3COOH = m/M = 9/60 = 0.15 (mol)
Theo phương trình => nNaHCO3 = 0.15 (mol)
mNaHCO3 = n.M = 84 x 0.15 = 12.6 (g)
==> mddNaHCO3 = 12.6x100/8.4 = 150 (g)
mdd sau pứ = 150 + 150 = 300 (g)
mCH3COONa = n.M = 0.15 x 82 = 12.3 (g)
C%dd muối sau pứ = 12.3 x 100/300 = 4.1 (%)
