Given: 200ml of 0.7890 M NH ₃ Water 100 ml of 007940 M CH3COOH AT: 4076 c , specific heat rabo = 4.104 Tgik Density = 1.03 gmit Total mass of solution Density * Volume 203 * Cloot loo) = loomI NHg Water + loom, CH3COOH = total volume y from co ho Q = 2064x4.104.J_ x 277. 76% A14.760 = 277.76€ Speafic locat - Llallsc 9. = 234 kJ / 2 234 8 240975 - 980.56 call foom equation ® Heat of heutralization - 1234 Xloop x L x 234824.92 - 0.79 = 297246209 KI since, heat is librated , heat of heutralization will be negative. lie Heat of neutralization = -2348-24.97 - 29724679 kJ
