Infinity Learn · Accepted Answer

Given, initial strength of acetic acid $$=$$ $$0.06$$ NFinal strength $$=$$ $$0.042N$$, volume given $$=$$ $$50$$ mL∴ Initial millimoles of $$CH3COOH=0.06$$×$$50=3$$ Final millimoles of $$CH3COOH=0.042$$×$$50=2.1$$∴ Millimoles of $$CH3COOH$$ adsorbed $$=3-2.1=0.9mmol$$                                                            $$=$$ $$0.9x60$$ mg                                                            $$=$$ $$54$$ mg
