When Four Hydrogen Nuclei Fuse to Make Helium, a Small

When four hydrogen nuclei fuse to make helium, a small amount of matter is lost. What is the mass difference and energy generated? The mass of hydrogen and helium nuclei are 1.67 × 10^-27 kg and 6.646 × 10^-27 kg, respectively.

A) 0.034 × 10^-27 kg, 3 × 10^-12 J
B) 0.022 × 10^-27 kg, 2 × 10^-12 J
C) 0.068 × 10^-27 kg, 6 × 10^-12 J
D) 0.011 × 10^-27 kg, 1 × 10^-12 J
