It seems like your question got cut off. If you're asking about the relative mass of a neutron (often denoted as "n"), it is approximately 1 Atomic Mass unit (amu), or about 1.008664915 amu. This makes it slightly heavier than a proton, though both have similar masses. If you meant something else, please provide more details!

The relative atomic mass of magnesium is approximately 24.305.
Relative atomic mass is determined by comparing the mass of an atom to one-twelfth of the mass of a carbon-12 atom, which is defined as exactly 12 atomic mass units (amu). To find it, you can use a mass spectrometer to measure the isotopic masses and their relative abundances, then calculate a weighted average based on these values. The formula used is: relative atomic mass = (isotopic mass × relative abundance) / total relative abundance for all isotopes. This gives a value that reflects the average mass of an atom of an element as found in nature.
Mass IS relative to the speed you are going.

It is a measure which gives the relative mass of an element (or compound) - relative to 12C having a mass of 12.
the relative atomic mass for the element potassium is 39.0983
The relative atomic mass of copper is approximately 63.55. To calculate the relative formula mass of copper, you sum the atomic masses of its atoms, which in this case would just be the atomic mass of copper. Therefore, the relative formula mass of copper would be 63.55.

The relative formula mass of iodine is 253.8 g/mol.
Use the relative atomic/molecular/molar mass, which is a measure of the mass (in grams) of one mole of an atom/molecule/entity. This is the case because one mole is defined as the number of atoms of carbon-12 that weigh 12 grams. Mr (relative molecular/molar mass) is measured in grams per mole (g/mol). As such you can use the equation: m = Mr x n Where m is the mass in grams Mr is the relative molecular mass in g/mol n is the number of moles The Mr of a molecule is the sum of the Ar (relative atomic mass) of all of the atoms in that molecule. Where the isotope is known, exact values can be used instead. For example, water, H2O, has an Mr of 18, as this is the sum of the mass of oxygen (16) and two hydrogens (1+1). Therefore 36g of water must contain 2 moles of water, using the equation above (rearranging for n, n=36/18=2).
