Answers
79.904 amu
79.904 amuBromine has two naturally occurring isotopes (Br-79 and Br-81) and an atomic mass of 79.904 amu.
Answer:
Molar mass, also referred as the Molecular weight, is the mass of one mole of the substance. It is expressed in the units of gmol−1
.
- We need to follow the following steps to calculate the molar mass.
- First, we have to identify the formula of a given compound or molecule.
- Then determine the number of moles of atoms present in the given compound or molecule.
- we have to multiply the mass of each atom with the number of moles of the atom.
- This has to be done for every element present in the compound.
- Finally add all these values.
- The obtained value is expressed in gmol−1
.
Now, consider the given Bromine trioxide BrO3
:
Molar mass of Bromine trioxide = molar mass of bromine + molar mass of oxygen
Molar mass of Bromine trioxide = 79.9+3×16.0=127.9gmol−1
Therefore, the molar mass of Bromine trioxide is 127.9gmol−1
Note: We must always remember that molar mass is different from the molecular mass. Now let us compare molar mass with Molecular mass:
MOLAR MASS MOLECULAR MASS
Molar mass is referred to as the mass of one mole of the substance. Molecular mass is the mass of the molecule.
It is expressed in the unit of gmol−1
. It is expressed in the unit of am
It is also known as Molecular weight. It
determines the mass of a single molecule.
