I have no idea how to set up these equations. If someone would help me set them up, I could do the rest! Thanks!
A sample of Mg (specific heat = 1.024-J/g°C) weighing 209.9-g is boiled in water at sea level until it reaches 100.0°C.
The sample is dumped into a coffee cup containing an unknown mass of water that had reached equilibrium temperature 24.6°C.
The temperature of the water and Mg rose to 43.5°C.
Assuming that no heat is absorded by the coffee cup, what was the mass of the water in the coffee cup. (in grams)
A sample of Al (specific heat = 0.900-J/g°C) weighing 227.8-g is boiled in water at sea level until it reaches 100.0°C.
The sample is dumped into a coffee cup containing 63.8-g of water that had reached equilibrium temperature 24.6°C.
The temperature of the water rose. Assuming that no heat is absorded by the coffee cup, what was the final temperature in°C?
