Einstein Mass-Energy Relationship

Useful conversions• 1kg=6.022x1026 amu• 1J=1 kg m2/s2

• Example- Find the binding energy of 19F• We found the mass defect of 19F to be 0.1587amu

• Converting:

• Filling in to E=mc2 (remember Δm will be negative, take the absolute value of it before filling it in)
