Given that,
The specific heat of acetic acid is 2.18 J/g°C
Mass, m = 47.0 g
The temperature increases from 25.5 °C to 91.6 °C.
To find,
The heat needed to raise the temperature.
Solution,
The heat need to raise the temperature is given by :
[tex]Q=mc\Delta T\\\\Q=47\times 2.18\times (91.6 -25.5)\\\\=6772.60\ J\\\\\text{or}\\\\=6.77\ kJ[/tex]
So, 6.77 kJ of heat is need to raise the temperature.
