What is the molar mass for-manganese?
The atomic weight of manganese (Mn) is 54,938 044(3).
What is the molecular mass of manganese?
Manganese is a metal element. Atomic mass of it is 55.
If an atom has a number of 25 and an atomic mass of 55?
It is an atom of the element manganese (symbol - Mn).
What is the mass of an element?
The mass number of an element is the atomic mass rounded to the nearest whole number. For Example, if the atomic mass is 54.94 (Manganese [Mn]), then the mass number will be 55. You can use the mass number to calculate the amount of neutrons in an isotope.
Atomic mass of manganese?
The atomic number of manganese is 25. The atomic weight of Mn is 54.93805 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!25
What element has an atomic mass of 54.938?
Manganese (Mn)
What is the molar mass for-manganese?
The atomic weight of manganese (Mn) is 54,938 044(3).
What is the mass number of an isotope if it has an atomic number of twenty five?
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.
What is the molecular mass of manganese?
Manganese is a metal element. Atomic mass of it is 55.

Calculate the molar mass of KMn04?
The molar mass is:39,0983 (atomic weight of K) + 54,938044 (idem for Mn) + (15,999 . 4 for O) = 157,432344 g
Atomic mass of manganese?
The atomic number of manganese is 25. The atomic weight of Mn is 54.93805 grams per mole.See the Web Links to the left of this answer for a periodic table with more information about this element!25
What is the atomic number of MN?
Manganese is a metal element. Atomic number of it is 25.
How do you calculate the mass in grams of 2.5 mol Mn?
The atomic weight of manganese is 54,938 044.Mass in grams of 2,5 moles: 54,938 044 x 2,5 = 137,34511 g
How many neutrons in Mn-25?
In it's most stable form, 55 is its atomic mass. 55 overall - 25 protons = 30 neutrons
What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
