Inorganic chemistry studies the chemical compounds in inorganic, or non-living things such as minerals and metals.
The chemical formula for the product is RbBr.
Delta enthalpy = 2x386-3x1x432-3x942=-3350kJ/mol
2.4 x 10²² atoms
<h3>Further explanation</h3>
Atomic mass is the average atomic mass of all its isotopes
In determining the mass of an atom, as a standard is the mass of 1 carbon-12 atom whose mass is 12 amu
So the atomic mass obtained is the mass of the atom relative to the 12th carbon atom
mass single Uranium atom=4.7 x 10⁻²² g
then for 111 mg=0.111 g
