[tex]d_{CO2} = miu.acid/miu.CO2[/tex]
=> miu.acid = 1,68x44 = 74 g/mol
acidului monocarboxilic saturat = CnH2nO2
=> 14n+32 = 74 => n = 1
=> acidului monocarboxilic saturat = HCOOH
Vs.KOH = 200 mL = 0,2 L
Cm.KOH = 2M
stim ca Cm = niu/Vs
=> niu.KOH = CmxVs = 0,2x2 = 0,4 moli KOH
0,4 moli n moli
KOH + HCOOH --> HCOOK + H2O
1 1
=> n = 0,4 moli acid
din Cm => Vs.acid = n/Cm
= 0,4/0,1 = 4 L sol acid
