11. (challenge problem) A 6,355 gram ingot of uranium (c=0.12 J/g-°C) has a temperature of 1050°F and must be cooled down immediately. It is dropped into a bucket containing a mixture of water (c=4.18 J/g °C) and methanol (c=2.53 J/g °C) with a starting temperature of 39°F. After all of this, they settle to a final temperature of 115°F. If the water absorbed exactly 4 times as much energy as the methanol, how many kilograms of liquid were in the bucket? (hint: the temperature change for the water and methanol are the same)
