The correct answer is:
Let's see why.
1 amu corresponds to the mass of the proton, which is:
if we convert this into energy, using Einstein equivalence between mass and energy, we find:
Now we can convert it into electronvolts:
So, 1 amu = 934 MeV. Therefore, 3 amu corresponds to 3 times this value:

Answer:
Q = 59565 [J]
Explanation:
In order to calculate the amount of thermal energy needed we must use the following equation.
where:
m = mass = 150 [g]
Cp = 4.18 [J/g*°C]
Tfinal = 5 [°C]
Tinitial = 100 [°C]
Now replacing:
