Nuclear waste disposal is one of the major concerns of the nuclear industry. In choosing a safe and
stable environment to store nuclear wastes, consideration must be given to the heat released during
nuclear decay. As an example, consider the B-decay of 0sr (89.907738 amu):
90
Sr
90
Y + B
t12= 28.1 yr

Zirconium-90 (89.904703 amu) is a stable isotope.
Beginning with one mole of 90Sr, calculate the amount of heat released (in kilojoules) in one year
corresponding to the number of moles of 90$r decayed to 0Zr.
