To determine the number of bromine molecules that have a mass equal to 21.8 g, you first need to find the molar mass of Br2, which is 159.808 g/mol. Then, you can use this molar mass to calculate the number of moles in 21.8 g of Br2. Finally, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.

How many Br2O molecules of different masses naturally exist?
Bromine has 2 natural isotopesOxygen has 3 natural isotopesWhile there are 4 combinations of isotopes of bromine in this molecule, there are only 3 different masses of bromine: heavy-heavy, heavy-light, and light-light.Thus 3 x 3 = 9 different masses.
What is the the mass number for bromine?
Bromine is a non metal element. Mass number of it is 80.
Rank the molecules (listed below along with the abundances of the individual atoms) by the height of their peaks in the mass spectrum for BrCl.?
To rank the molecules by peak height in the mass spectrum for BrCl, consider the abundance of each atom in the molecule. The higher the abundance of bromine and chlorine atoms relative to the total number of atoms in the molecule, the higher the peak in the mass spectrum. Rank the molecules based on these proportions: BrCl molecule with highest abundance of bromine and chlorine atoms Br2Cl2 molecule with moderate abundance of bromine and chlorine atoms Br3Cl3 molecule with lower abundance of bromine and chlorine atoms
Why does bromine have different mass numbers?
Different isotopes of bromine have different numbers of neutrons, resulting in different mass numbers. Bromine-79 and bromine-81 are the two most common isotopes of bromine, with mass numbers of 79 and 81, respectively.
Aluminum will react with bromine to form aluminum bromide Al2Br6 What mass of bromine g is needed to form 1.42 mol of Al2Br6?
The gram formula unit or molar mass for aluminum bromide is 533.38.* Therefore, 1.42 moles has a mass of 757.4 grams. The mass of 6 moles of bromine atoms is 479.42. Therefore, the mass fraction of bromine in aluminum bromide is 479.42/757.4 or 0.633, and the mass in grams of bromine required to form 1.42 moles of aluminum bromide is 0.633 X 757.4 or 479 grams, to the justified number of significant digits (limited by the precision given for the number of moles.) ___________________ *This is equal to the sum of (2 times the gram atomic mass of aluminum) and (6 times the gram atomic mass of bromine).

Determine the number of bromine molecules present in the flask containing 0.120 of liquid bromine?
To determine the number of bromine molecules, you need to first convert the mass of liquid bromine to moles using its molar mass. Then, use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
How many moles are there in 160g of bromine molecules?
To find the number of moles in 160g of bromine molecules, we first need to determine the molar mass of bromine which is approximately 79.9 g/mol. Then, we can use the formula: moles = mass / molar mass. Therefore, moles = 160g / 79.9 g/mol ≈ 2 moles.
How many moles of bromine gas are in 37.7 grams?
To determine the number of moles of bromine gas in 37.7 grams, you need to divide the given mass by the molar mass of bromine. The molar mass of bromine is approximately 79.904 g/mol. So, 37.7 grams of bromine is equal to 0.471 moles (37.7 g ÷ 79.904 g/mol).
A flask contains 0.500 of liquid bromine Determine the number of bromine molecules present in the flask?
To find the number of bromine molecules in the flask, first determine the molar mass of bromine, which is 79.904 g/mol. Then, use Avogadro's number (6.022 x 10^23 molecules/mol) to convert the mass of bromine in the flask to the number of molecules. This will give you approximately 1.66 x 10^22 bromine molecules in the flask.
