you need to find the relative Atomic Mass. without that, you can't find that information unless given to you. basically, molar mass is a mole. a huge unit, but if you have that one "mole" of hydrogen atoms, you will have a equivalent of 1 gram
The molar mass is the sum of the atomic weights of elements contained in the molecule, expressed in g/mole.

∙ 10y agoThe molar mass of a compound is the sum of the atomic weights of the containing elements. Example for NaCl:
22,98976928 (atomic weight of sodium) + 35,45 (atomic weight of chlorine) = 58,43976928 (molar mass of sodium chloride)

∙ 9y agoIn order to determine the molar mass of an element, the atomic weight on the Periodic Table is sufficient. For a compound, on the other hand, the molar mass of the molecule needs to be calculated more in-depth. The chemical formula will tell you the number of each atom in the compound, and then the atomic weights of these elements must be multiplied by the number of those elements in the molecule, after which they are added together for the total.

∙ 10y agoThe molar mass is the sum of atomic weights of the contained chemical elements; as a example sodium sulfate (Na2SO4):
Molar mass = (2 x atomic weight of Na) + (atomic weight of sulfur) +
(4 x atomic weight of oxygen) = 142,04 (for the anhydrous salt)

How do you find the molar mass of an atom?
Molar mass is a term applied for molecules, not for atoms.
What is is the molar mass of 3.00 of NaCL and 1.50kg?
The molar mass of NaCl (sodium chloride) is 58.44 g/mol. To find the molar mass of 3.00 mol of NaCl, you would multiply 3.00 mol by the molar mass of NaCl. For the 1.50 kg, you would first convert the mass from kilograms to grams (1 kg = 1000 g), then divide the mass by the molar mass to find the number of moles.
How do you find the molar mass of HNO3?
The problem for nitric acid (HNO3). Molar mass would be 63.02g/mol
What is the molar mass of the sugar called glucose?
The molar mass of glucose is 180,16 g.
What is the mass of 2.6 g of magnesium and 1.6 g of oxygen?
The molar mass of magnesium is 24.31 g/mol, while the molar mass of oxygen is 16 g/mol. To find the mass of 2.6 g of magnesium, you can divide 2.6 g by the molar mass of magnesium (24.31 g/mol) and multiply by Avogadro's number to find the number of moles. Similarly, you can do the same calculation for 1.6 g of oxygen and then sum up the molar masses to find the total mass.
How do you find the molar mass of an atom?
Molar mass is a term applied for molecules, not for atoms.
How do you find the molar mass of an elemnt?
Molar mass is a term applied for molecules, not for atoms.
The molar mass of C3H8O2 is?
to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu) to find molar mass you add the molar mass of the carbons 3(amu)+ molar mass of the hydrogens 8(amu)
What is lithium's molar mass?
Lithium's molar mass is 6.941g/mol. To find the molar mass of an element, take the atomic weight on the periodic table in grams.
Is avogadro's number the same as molar mass?
no youre thinking of molar mass and atomic weight although you use avogadro's number to find molar mass
How find percent compsotion of oxygen in Na2O?
To find the percent composition of oxygen in Na2O, find the total molar mass of the compound. Then, divide the molar mass of oxygen by the molar mass of the compound, and multiply by 100% to get the percent oxygen.
How do you find how many moles are in a solute?
Yoy need to know the molar mass of this solute and the mass of the solute:moles = total mass/molar mass
What is the theoretical percentage of water of hydration in cacl2-2h20?
1. Find the molar mass of the hydrate (Calcium Chloride Dihydrate).Find the molar mass of water and the anhydrate (anhydrate + water = hydrate); add the molar mass values of each to find the molar mass of the hydrate.Molar Mass CaCl2: 110.98g+ Molar Mass H2O: 36.04g*Molar Mass CaCl2 * 2H2O: 147.01gFinding Molar Mass# atoms element A * atomic mass element A = Mass A# atoms element B * atomic mass element B = Mass B... etc.Add up all the mass values and you have the value for molar mass. Do this for both the anhydrate and the water molecules. Add these values together to find the molar mass of the hydrate.Molar Mass Anhydrate + Molar Mass Water Molecules* = Molar Mass Hydrate* Tip: the molar mass of water for all hydrate calculations is 18.02g x number of water molecules. This number may be useful to remember on the day of the test or while doing practice problems.*2. Calculate the percentage of water in hydrate.Divide the molar mass of water by the molar mass of the hydrate, and multiply result by 100%.36.04g147.01g x 100%Percent water in hydrate is 24.52%.
What is is the molar mass of 3.00 of NaCL and 1.50kg?

For the 1.50 kg, you would first convert the mass from kilograms to grams (1 kg = 1000 g), then divide the mass by the molar mass to find the number of moles.
What is the mass percent of aluminum in aluminium chlorohydrate?
In Al2Cl(OH)5 Mass percent is 31.03% You find it by adding up the total molar mass (found on the periodic table) and then adding up the molar mass of Al you have. Finally you divide the molar mass of Al by the total molar mass.
Determine the mass of 21 mol N?
number of moles = mass/molar mass mass = number of moles x molar mass 21mol x 14gmol-1 = 294g molar mass of Nitrogen is 14, which you can find on a periodic table
How do you find moles of hydrogen?
Since molar mass of hydrogen is 1g , the no. of moles = mass of hydrogen given. or No. of moles= Given mass of substance/Molar mass of substance
