What is the mass of a neutron in mass units?

Mass of 1 neutron=1.008664 from my notes altough i'd double check.Lol for the answer 1obviously going to be used to calculate energy difference :)

The mass of a proton is about 1.007 276 466 amu. The mass of a neutron is about 1.008 664 916 amu.

1 atomic mass unit (amu) = 1.66053886 × 10^-27 kg. Try the following: go to Google, and type in the search box: 1 amu to kilograms and you'll get the answer. It works on a lot of units: 1 hp to...

Mass of a Proton = 1.6726x10-27 kg Mass of a Neutron = 1.6749x10-27 kg The ratio is then: 0.99864

There is nothingwith a mass of exactly 1 a.m.u.The a.m.u. is defined by Carbon 12 having exactly 12 a.m.u s, and it is the only isotope with an exactly integral number of them.Having said that,...
