The atomic weight of zinc is: 65,38
The atomic weight of fluorine is: 18,998 403 2
The molecular mass of zinc difluoride is by consequence:
65,38 + 2 x 18,998 403 2.
And M= 103,406 g/mol (for the anhydrous molecule)

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.
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.
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 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

Zn= 65.4 F2= 19 x 2= 38 38+ 65.4= 103.4 molar mass of of znf2 is 103.4 grams
How do you find the molar mass of an elemnt?
Molar mass is a term applied for molecules, not for atoms.
How do you find the molar mass of an atom?
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?

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 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.
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.
