Answer:
The answer to your question is 144 kg
Explanation:
Data
Q = 8669 kJ
T1 = 75°F
T2 = 195°F
Cp = 0.897 J/(g°C)
m = ?
Formula
Q = mCp(T2 - T1)
Process
1.- Convert temperature to °C
T1 = (75 - 32) / 1.8
= 43/1.8
= 23.9°C
T2 = (195 - 32) / 1.8
= 163/1.8
= 90.6°C
2.- Solve for m
m = Q / Cp(T2 - T1)
3.- Substitution
m = 8669000 / 0.897(90.6 - 23.9)
4.- Simplification
m = 8669000 / 59.83
5.- Result
m = 144893.66 g or 144.9 kg
