ethanoic acid is CH3COOH or HAc.
K2CO3 + 2HAc ==> 2KAc + H2O + CO2
mols K2CO3 = M x L = ?
mols HAc = 2*mols K2CO3 (you get that form the coefficients in the balanced equation).
Then M HAc = mols HAc/L HAc = ?
K2CO3 + 2HAc ==> 2KAc + H2O + CO2
mols K2CO3 = M x L = ?
mols HAc = 2*mols K2CO3 (you get that form the coefficients in the balanced equation).
Then M HAc = mols HAc/L HAc = ?
