Part E
In an insulated container, 0.50 \rm kg of water at 80^\circ \rm C is mixed with 0.050 \rm kg of ice at -5.0^\circ \rm C. After a while, all the ice melts, leaving only the water. Find the final temperature T_f of the water. The freezing point of water is 0^\circ \rm C.
Express your answer in degrees Celsius to two significant figures.
Okay, so I know I have to use heat of fusion, Q=mL, and I know Qnet = 0, but I am not sure how to combine these info together.
What I have is. . . (I converted everything to K first)
m_1c_1deltaT + m_2c_2deltaT + mL = 0
(.5kg)(4184J/kgK)(T_f-353K)+(.05kg)(2050J/kgK)(T_f-286K)+mL = 0
I am not sure if I have plugged in the values correctly and I don't know what m and L is. . .
Please help?
