a/
PTPU
Na2CO3+ 2CH3COOH\(\rightarrow\) 2CH3COONa+ CO2\(\uparrow\)+ H2O
có: nNa2CO3= \(\frac{10,6}{106}\)= 0,1( mol)
b/ thep PTPU có: nCO2= nNa2CO3= 0,1( mol)
\(\Rightarrow\) VCO2= 0,1. 22,4= 2,24( lít)
c/ theo ptpu có: nCH3COOH= 2nNa2CO3= 2. 0,1= 0,2( mol)
\(\Rightarrow\) CM CH3COOH= \(\frac{0,2}{0,1}\)= 2M
nNa2CO3= 10.6/106=0.1 mol
Na2CO3 + 2CH3COOH --> 2CH3COONa + CO2 + H2O
0.1________0.2________________________0.1
VCO2= 0.1*22.4=2.24l
CM CH3COOH= 0.2/0.1= 2M
