The number of theoretical plates is the number of discrete distillations that would have to be performed to obtain an equivalent separation of a discrete plate. This number is commonly used as a measure of separation efficiency and is a useful when comparing the performance of various chromatographic columns.
One theoretical plate is equivalent to one vaporization-condensation cycle, which is equivalent to one simple distillation. Thus a fractionation column that can attain the equivalent of three simple distillations would be said to have three theoretical plates.
The heat required to raise the temperature to a specific temperature change of a sample is related to the specific heat capacity of the substance. In this case, the heat can be calculated through mCpΔT = 350 g * 0.39 J/g C *25 C. This is equal to 3412. 5 Joules. Closest answer is C.
