A 25.0g ice cube at its melting point is added to a calorimeter water at 25.4ºC. When thermal equilibrium is reached, the final temperature of the mixture is at 15.0ºC. The original volume of water in the calorimeter was? This is all the data given. A. 93.4mL B. 136mL C. 209mL D. 228mL I used the mcΔt = mcΔt formula, but the answer didn't seem to match the options given in my assignment. I've been trying to figure this out for more than an hour now...please someone help, if im using the wrong formula correct me.
