a , 2CH3COOH + Na2CO3 -> 2CH3COONa + H2O + CO2
b , nCH3COOH = \(\frac{100.10\%}{60}=\frac{1}{6}\left(mol\right)\)
=> nCO2 = 1/12(mol) = nNa2CO3 => VCO2 = 28/15 (l)
c , mNa2CO3 = 106.1/12=53/6(g)
mCH3COOH= 100*10/100=10g
nCH3COOH= 10/60=1/6 mol
2CH3COOH + Na2CO3 --> 2CH3COONa + CO2 + H2O
1/6____________1/12___________________1/12
VCO2= 1/12*22.4=28/15l
mNa2CO3= 1/12*106=53/6g
mdd Na2CO3= 53/6*100/5=530/3g
