6. Consider a very small cube of ice having density 0.9 g/cm3, and cooled to 77 K in liquid nitrogen. In the presence of the world's strongest magnetic field (45 T), 50.03% of the protons are spin up and 49.97% of the protons are spin down. The magnetic moment of the droplet is M = 5.09 X 10'7 I/T, which is aligned with the external magnetic field. What is the volume of the droplet
