What unit is the molar mass of a molecule in?
The molar mass is expressed in grams.
The mass of a mole of a substance expressed in grams is called a?
molacular mass
Which term is used to represent the mass of 1 mole of molecules of a substance?
This is equal to the molar mass of this substance.
If 0.274 moles of a substance weighs 62.5 g what is the molar mass of the substance in units of gmol?
The molar mass is 228,1 g.
How does one determine a molecular formula from the empirical form?
molar mass of unknown/molar mass of empirial = # of empirical units in the molecular formula. Example: empirical formula is CH2O with a molar mass of 30. If the molar mass of the unknown is 180, then 180/30 = 6 and molecular formula will be C6H12O6
What unit is the molar mass of a molecule in?
The molar mass is expressed in grams.
The mass of a mole of a substance expressed in grams is called a?
molacular mass
What is the relationship between the molar mass and atomic mass?
The molar mass is the mass of a molecule - sum of the masses of contained atoms, expressed in grams.The atomic mass is the mass of an isotope expressed in unified mass atomic units.The atomic weight is the mass of a chemical element (taking into account its isotopes) expressed in unified mass atomic units; also known today as relative atomic mass. IUPAC maintain the term (standard) atomic weight.
what are the units of molar mass?
g/mol
Which term is used to represent the mass of 1 mole of molecules of a substance?
This is equal to the molar mass of this substance.
Average weight of an element expressed in atomic mass units?
Average weight of an element expressed in Atomic Mass units.
What is the mass of expressed km?
Mass is not expressed in kilometers (km). That is a measure of distance. Mass is expressed in units of kilograms (kg)
What do you do to convert grams to moles?
The molar mass of a compound is expressed in grams.
What is the difference in molar mass and atomic mass?
molar mass is the actual mass of the one atom but relative mass is the average isotopes of the atoms.------------------------------------------Atomic mass is the mass of an isotope, expressed in atomic mass units.Molar mass is the mass of molecule, calculated from the atomic weights of the contained chemical atoms, expressed in grams.
If 0.274 moles of a substance weighs 62.5 g what is the molar mass of the substance in units of gmol?
The molar mass is 228,1 g.
What is the formula of atomic mass?
The formulaic conversion between atomic mass units and SI mass in grams for a single atom is:where Mu is the Molar mass constant and NA is Avogadro's number.The number of atoms in a mole is calledAvogadro's number, the value of which is approximately 6.022 × 1023 mol-1One mole of a substance always contains almost exactly therelative atomic mass or molar mass of that substance (which is the concept of molar mass), expressed in grams ..>> that's all thank you!! :)) ~ ^^
