The unit for the atomic masses (and also for atomic weights) is the unified atomic mass unit equivalen to to 1/12 of the Atomic Mass of the carbon isotope carbon-12 in normal state or 1,660 538 921(73)×10−27 kg.

More commonly used is a relative unit; this one assumes that C12 weighs exactly 12 units, and all other nuclides are expressed in these units.

How is the molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
The molar mass of an element is equal to?
The element's average atomic mass.
How is the number of moles of an element determined from the known mass?
The molar mass is the measurement of mass per one mole of a substance. If the mass of a matter is known, divide it from the molar mass to obtain the number of moles.
The molar mass of an element is the mass of one?
the mole of the element
What are the steps for calculating molar mass of compound?
molar mass is the atomic mass of the element. it's on the Periodic Table. you just have to add them up. unless you want to calculate the number of moles in a compound, in that case: moles = mass/molar mass
How is the molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
The molar mass of an element is equal to?
The element's average atomic mass.
How would we know how many moles are in a certain element?
number of moles = mass of the element/molar mass of the element
How is molar mass of an element determined?
the Atomic Mass in g/ml is the molar mass of the element
How is a number of moles of an element determined from a known mass?
The number of moles is mass in g/molar mass in g.
Calculate the atomic mass of an element?
By taking the wieghted averages of naturally occurring isotopes of that element. :)

What does an element's molar mass tell you about the element?
Molar mass is the mass in grams of 1 mol of subatace, idk if that helps
The molar mass of an element is the mass of one?
the mole of the element
Which element N S Pu or Cl contains the least moles of atoms in a 5.0g sample?
Number of moles = mass / molar mass, so the answer is the one with the greatest molar mass. This is plutonium.
What is the molar mass potassium?
The molar mass of the element potassium is 39 g/mol.
