The atomic weight of manganese (Mn) is 54,938 044(3).
The molecular mass of manganese is approximately 54.94 grams per mole.
To calculate the average relative atomic mass of neon, you would take the percentage abundance of each isotope of neon and multiply it by the atomic mass of that isotope. Then, sum these products together to get the average relative atomic mass of neon.
There are 13 neutrons in Mn-25. This can be calculated by subtracting the atomic number (number of protons) from the mass number (sum of protons and neutrons), giving you 25 - 13 = 12 neutrons.

Manganese (Mn)
The atomic weight of manganese (Mn) is 54,938 044(3).
Manganese or Mn has an atomic number of 25 (25 protons). The stable atom has 30 neutrons, so the stable atomic mass is 55 amu. The mass for one of its isotopes depends on how many neutrons it has. For instance, the next most stable isotope of Mn is Mn53 with only 28 neutrons so it has an atomic mass of 53 amu.
To find the mass of 1.02×10^24 atoms of Mn, you need to calculate the atomic mass of Mn from the periodic table (54.938045 g/mol). Then, divide the number of atoms by Avogadro's number to get moles, and finally multiply by the atomic mass to get the mass in grams. The mass of 1.02×10^24 atoms of Mn would be approximately 94.64 grams.
The molecular mass of manganese is approximately 54.94 grams per mole.
The molar mass is:39,0983 (atomic weight of K) + 54,938044 (idem for Mn) + (15,999 . 4 for O) = 157,432344 g
To calculate the average relative atomic mass of neon, you would take the percentage abundance of each isotope of neon and multiply it by the atomic mass of that isotope. Then, sum these products together to get the average relative atomic mass of neon.
The atomic number of manganese (Mn) is 25, indicating that it has 25 protons in its nucleus.

The atom has 25 protons in its nucleus based on the atomic number. The atomic mass of 55 is the sum of protons and neutrons in the nucleus. Therefore, the atom has 30 neutrons (55 - 25 = 30).
The mass of an element is determined by the total number of protons and neutrons in its nucleus. This mass is typically measured in atomic mass units (amu) and is an average of all the naturally occurring isotopes of that element.
