Phileas Fogg, the character who went around the world in 80 days, was very fussy about his bathwater temperature. It had to be exactly 38.0 degrees Celsius. You are his butler, and one morning while checking his bath temperature, you notice that it's 42.0 degrees Celsius. You plan to cool the 100.0 kg water to the desired temperature by adding aluminum duckie originally at freezer temperature (-24.0 degrees Celsius). Of what mass should Aluminum duckie be? Assume that no heat is lost to air.

Actually this is a homework question... and you want someone else to do it for you.
