Kelvin is a temperature scale designed so that zero degrees K is defined as absolute zero (at absolute zero, a hypothetical temperature, all molecular movement stops - all actual temperatures are above absolute zero) and the size of one unit is the same as the size of one degree Celsius.
the answer equals to 29000
Atomic number=number of protons (and electrons, but that doesn't matter in this answer)
Atomic mass=number of protons+number of neutrons
Atomic mass=atomic number+number of neutrons
Atomic mass-atomic number=number of neutrons
88-38=number of neutrons
number of neutrons=50
