How many BTU's does it take to turn 32 degree water into 32 degree ice?
I assume you mean degrees Fahrenheit. First you must remove heat to make ice not add it. Next, the amount depends largely on the quantity (mass) of water being frozen. Water has a enthalpy of fusion of 333.55 KJ / Kg This means that for each kilogram of water you must remove 333.55 kilo-Joules to make it into ice. A conversion factor of 1 : 0.9478 between KJ and BTU gives us 316.14 BTU per Kilogram of water.

What is the mass of 150 mL of water after it has frozen?
A milliliter of water, by definition, weighs one milligram. That is its mass. When 150 mL of water freezes, the volume of the water will change, but the mass will remain the same. So 150 mL of water will weight 150 mg, no matter what state of matter it's in.
