In chemistry, the molar mass, M, is a physical property. It is defined as the mass of a given substance (chemical element or chemical compound) divided by its amount of substance.
The molar mass of atoms of an element is given by the atomic weight of the element multiplied by the molar mass constant, M
u = 1×10−3 kg/mol = 1 g/mol:M(H) = 1.007 97(7) × 1 g/mol = 1.007 97(7) g/molM(S) = 32.065(5) × 1 g/mol = 32.065(5) g/molM(Cl) = 35.453(2) × 1 g/mol = 35.453(2) g/molM(Fe) = 55.845(2) × 1 g/mol = 55.845(2) g/mol.
Multiplying by the molar mass constant ensures that the calculation is dimensionally correct: atomic weights are dimensionless quantities(i.e., pure numbers) whereas molar masses have units (in this case, grams/mole).
To find the molar mass of an atom, you need to add up the atomic masses of all the atoms in its chemical formula. This can be determined from the periodic table. The unit for molar mass is grams per mole.
Molar mass of it is 32gmol-1. It is twice than an atom.
Molar mass of the hydroxide anion, OH-, is 17.00734 g/mol
Atomic mass and molar mass are similar concepts but not the same. Atomic mass refers to the average mass of an atom of an element, while molar mass is the mass of one mole of a substance. The mass number of particles can be the same in certain cases, such as isotopes of the same element which have the same number of protons and different numbers of neutrons.
The atomic mass of an atom is the sum of the number of protons and neutrons in the nucleus. It is generally expressed in atomic mass units (amu). The atomic mass is important for determining the overall mass of an atom and for calculating molar masses in chemical reactions.

The atomic number.
Molar mass of it is 32gmol-1. It is twice than an atom.
The molar mass is the sum of the atomic weights of atoms contained in the molecule.
Molar mass of an element is the atomic weight on the periodic table in grams. 1 mole of atoms of an element is 6.022 x 1023 atoms. To find the mass of one atom of an element, divide the element's molar mass by 6.022 x 1023 atoms.Example:Sodium, Na, has a molar mass of 22.989770g/mol (atomic weight in grams)1 mole Na atoms = 6.022 x 1023 atomsSolution:22.989770g/mol x 1mol/6.022 x 1023 atoms = 3.818 x 10-23g/atom
Ammonia sulfide is (NH4)2SO4. And the molar mass is 116 g mol-1.
Molar mass of the hydroxide anion, OH-, is 17.00734 g/mol
The molar mass of calcium oxide is 56.077 grams per mole
Ammonium phosphate ((NH4)3PO4) contains one phosphorus atom in the formula. To calculate the percent composition by mass of phosphorus, you need to find the molar mass of phosphorus and the molar mass of the entire compound. Then, divide the molar mass of phosphorus by the molar mass of the compound and multiply by 100 to get the percentage.
The molar mass of the lightest alcohol, methanol, is 32.04 grams per mol. No alcohol has a molar mass of 4.75 grams. To find the molar mass of a substance, you sum the mass of every atom that makes up your compound. For methanol, you add the mass of three hydrogens, a carbon, and an oxygen atom. An alcohol group, more properly a "hydroxyl," consists of an oxygen and a hydrogen and contributes about 17 grams per mol to the molar mass (about 16 g/mol for an oxygen atom and 1 for a hydrogen). Hope this helps!
The molar mass aluminum chloride is 133,34 g (for the anhydrous salt).
The molecular formula of the compound CH with a molar mass of 42.0 g/mol is C3H3. This can be calculated by dividing the molar mass by the molar mass of a carbon atom (12 g/mol) to determine the number of carbon atoms, and then assigning the remaining mass to hydrogen atoms.
