nó là axit axetic á :v
a) Mg + 2CH3COOH --> (CH3COO)2Mg + H2
\(n_{H_2}=\dfrac{6,72}{22,4}=0,3\left(mol\right)\)
PTHH: Mg + 2CH3COOH --> (CH3COO)2Mg + H2
0,6<-------------0,3<-------0,3
=> \(V_{dd.CH_3COOH}=\dfrac{0,6}{2}=0,3\left(l\right)\)
c) \(m_{\left(CH_3COO\right)_2Mg}=0,3.142=42,6\left(g\right)\)
d)
PTHH: KOH + CH3COOH --> CH3COOK + H2O
0,6<-----0,6
=> mKOH = 0,6.56 = 33,6 (g)
=> \(m_{dd.KOH}=\dfrac{33,6.100}{5}=672\left(g\right)\)
