What is the the mass number for bromine?
Bromine is a non metal element. Mass number of it is 80.
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.
An atom of bromine has a mass about four times greater than that of an atom of neon which comparison of the relative numbers of bromine and neon atoms in 1000 g of each element?
In 1000g of bromine, there are fewer atoms compared to 1000g of neon because the atomic mass of bromine is higher. This means that the same mass of bromine contains a lower number of atoms compared to neon due to the higher atomic mass of bromine.
Which is the percent composition of bromine in the compound NaBr?
The percent composition of bromine in NaBr is approximately 77.7%. This is calculated by dividing the molar mass of bromine by the molar mass of NaBr and then multiplying by 100.
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).
What is the the mass number for bromine?
Bromine is a non metal element. Mass number of it is 80.
What is the Mass number of a bromine atom?
Bromine has an approximate atomic mass of 79.904.
What is the relative atomic mass of bromine?
Bromine is a non meta element. Atomic mass of it is 80.
What is Bromine atomic mass?
Bromine is a metal element. Atomic mass of it is 79.90.
What is the atomic mass of bromine-97?
Bromine is a non metal element. Atomic mass of it is 80.
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.
What is the mass in atoms of 350 mol of bromine?
To find the mass of 350 mol of bromine, you need to multiply the number of moles by the molar mass of bromine. The molar mass of bromine is approximately 79.9 g/mol. So, 350 mol * 79.9 g/mol = 27965 g. Therefore, the mass of 350 mol of bromine is 27965 grams.
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)
How do you calculate the atomic mass of bromine?
To calculate the atomic mass of bromine, you would take the weighted average of the isotopic masses of bromine's isotopes, considering their relative abundance in nature. The atomic mass of bromine is approximately 79.904 u.
What is the atomic number and mass number of bromine?
Bromine is a non meta element. Atomic mass of it is 80.
An atom of bromine has a mass about four times greater than that of an atom of neon which comparison of the relative numbers of bromine and neon atoms in 1000 g of each element?
In 1000g of bromine, there are fewer atoms compared to 1000g of neon because the atomic mass of bromine is higher. This means that the same mass of bromine contains a lower number of atoms compared to neon due to the higher atomic mass of bromine.
25.0 mL of bromine weighs 77.58 g What is the density of bromine?
The density of bromine can be calculated by dividing the mass of bromine by its volume. In this case, the mass of bromine is 77.58 g and the volume is 25.0 mL. So, the density of bromine is 3.10 g/mL.
