The mass of a protonse)z24gh pc3u mu6s 3c is ap0 i*u)ssncj l9d) ,ravx 6i:$1.6726 \times 10^{-27} \; kg$ and the mass of a neutron is $1.6749 \times 10^{-27} \; kg$. A proton captures a neutron forming a deuterium nucleus. One would expect the mass of this nucleus to be
A. equal to $(1.6726 + 1.6749) \times 10^{-27} \; kg$.
B. less than $(1.6726 + 1.6749) \times 10^{-27} \; kg$.
C. greater than $(1.6726 + 1.6749) \times 10^{-27} \; kg$.
D. any of these; it depends on the energy released during the capture.
