What is the molar mass for tribromine oxide?
The molar mass of tribromine oxide (Br3O) can be calculated by adding up the atomic masses of its constituent atoms. The molar mass of bromine (Br) is approximately 79.90 g/mol, and the molar mass of oxygen (O) is approximately 16.00 g/mol. Therefore, the molar mass of tribromine oxide is approximately 249.70 g/mol.
Can one use the average mass of elemental bromine for the atomic mass of bromine?
Yes, that is what is used. Bromine is I think ~51:49 ratio of Br79 and Br81. Therefore it is somewhere in between (79.9g/mol)
The mass of a sample of nickelaverage atomic mass 58.69 amu is 11.74g how many atoms does it contain?
the number of atoms is equal to the mass of the sample divided by its molar mass times one mole 11.74g / 58.69g/mol * 6.02*1023 atoms/mol = 1.2*1023 atoms approximately
Which are isotopes of hydrogen and chlorine?
Chlorine has isotopes with mass numbers ranging from 32 to 40. There are two principal stable isotopes, 35Cl (75.77%) and 37Cl (24.23%), giving chlorine atoms in bulk an apparent atomic weight of 35.5 g/mol.
What is mass in grams of a single atom of bromine?
The molar mass of bromine is approximately 79.9 grams/mol. Since one mole of any substance contains Avogadro's number of particles (6.022 x 10^23), the mass of a single bromine atom is approximately 79.9 grams/mol divided by 6.022 x 10^23, which is approximately 1.33 x 10^-22 grams.

What is the mass of one mole atoms?
The mass depends on the element whose atoms are concerned. For eg, 1 mol Helium atoms have mass 4 g 1 mol Neon atoms have mass 20 g.

How many atoms are in 1.54 moles of Bromine?
1.54 (mol Br2) * 6.022*10+23 (molecule/mol Br2) * 2 (atoms Br/molecule Br2) =1.85*1024 atoms in 1.54 mole Br2
How many moles are in 0.476 grams of bromine?
Mol = mass/Ar (relative atomic mass)For Bromine Ar is 79.9 g/mol.Mol= 0.476/79.9 = 5.96x10-3
The mass of a sample of nickelaverage atomic mass 58.69 amu is 11.74g how many atoms does it contain?
the number of atoms is equal to the mass of the sample divided by its molar mass times one mole 11.74g / 58.69g/mol * 6.02*1023 atoms/mol = 1.2*1023 atoms approximately
What is the molar mass for tetraphosphorus trisulfide P4S3?
To determine the molar mass for any compound, you multiply the molar mass of each element (atomic mass in grams) times its subscript, which represents the number of atoms of that element. Then add the result for each element. Molar Mass of P4S3 (4 atoms x 30.974g/mol P) + (3 atoms x 32.06g/mol S) = 123.90g/mol P + 96.18g/mol S = 220.08g/mol P4S3
What is the mass in grams of 1mole of oxygen?
The mass of 2.000 mol of oxygen atoms is 32.00 grams.
Are the number of atoms of bromine in 1 mol Br2 equal to avogadro's number?
No the number of ATOMS in 1 Bomine MOLECULE Br2 is twice Avagadro's number.
How many atoms do six grams of diamond have?
Diamond is made of up carbon. So, it has a molar mass of 12 g/mol. 6 g/mol / 12 g = 0.5 mol 0.5 mol * 6x10^23 atoms/mol = 3x10^23 atoms There are 3x10^23 atoms in six grams of diamond.
How many atoms are in 0.0010 grams of calcium?
(g) -> moles = x(g) * (1 mol/molar mass)Moles -> atoms = x(mol) * (6.022*10^23/1 mol)
What is the molar mass of potassium bromide?
Potassium bromide is KBr, so by adding together their molar masses, we get 39+80=119gmol-1
