Each chemical element has a specific atomic weightexpressed in Atomic Mass units.
Each isotope of a chemical element has a specific atomic mass expressed in atomic mass units. This mass can be determined by adding the number of neutrons (which each weigh one atomic mass unit or amu) and the number of protons (which each weigh one amu as well).

How is the molar mass of a compound determined?
By adding the average atomic masses of all elements in the compound.
How are molarity and molar mass related for a compound?
The molar mass of a substance is measured in grams per mole written as gmol-1. It is worked out using the Mole formula by dividing mass in grams by the amount in moles.
The molar mass of an element is equal to?
The element's average atomic mass.
The mass of a mole of a substance expressed in grams is called a?
molacular mass
How is the periodic table useful in finding molar mass?
Atomic mass is listed on the periodic table.The molar mass of a substance is the mass of 1 mol (the SI unit for the basis SI quantity amount of substance, having the symbol n) of the substance. This has a numerical value which is the average molecular mass of the molecules in the substance multiplied by Avogadro's constant approximately 6.022×1023. The most common units of molar mass are g/molbecause in those units the numerical value equals the average molecular mass in units of u.Conversion factor of average molecular mass to molar mass:molar mass = average molecular mass × ((1/6.022)×10-23g/u)×(6.022×1023/mol)ormolar mass in g/mol= average molecular mass in u

How are Avogadro constant average atomic mass and molar mass related?
The average atomic mass of an element is the weighted average mass of an atom (including all its isotopes). This is related to the molar mass, because molar mass is the weight of 1 mole of something (atoms, molecules, etc...). 1 mole = 6.022 x10^23 = avogardro's constant.
The rate of effusion of Argon was measured to be 0.218mols at a certain temperature Calculate the rate of effusion of helium gas (Molar mass of Ar=40,Molar mass of Helium =4)?

The effect of vapor condensation in the neck a beryl type pipet have on the reported molar mass?
it would give a higher molar mass b/c we are actually measuring the condensed liquid so the measured pipet would give higher mass. the higher the pipet is the higher molar mass.
The molar mass of an element is equal to?
The element's average atomic mass.
What is the molar mass of sulfur?
The molar mass of sulfur is 32.065. Molar mass is the mass per mole of a substance. In other words, Molar Mass = Mass/Amount of Substance.
The mass of a mole of a substance expressed in grams is called a?
molacular mass
What is the molar mass of SiC?
Molar Mass of Carbon + Molar Mass of Silicon = Molar Mass of SiC. 12.0107 + 28.0855 = 40.0962 g / mol.
What is the molar mass of the sugar called glucose?
The molar mass of glucose is 180,16 g.

The molar mass of a mole of lead?
molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g molar mass =207.2 g / mol no. moles = mass/ molar mass moles = 1 1(207.2) = mass mass of 1 mole lead is 207.2g
