Explanation:
a molecule containing a very large number of atoms, such as a protein, nucleic acid, or synthetic polymer.
The moles which were measured out is calculated using the following formula
moles = mass/molar mass
molar mass of CuBr2.4H20 = 63.5 Cu + ( 2 x79.9) br + ( 18 x4_) h20 = 295.3 g/mol
moles is therefore= 5.2 g/ 295.3 g/mol= 0.0176 moles
The number of moles in 32.5g of aluminum chloride is approximately 0.250 moles.
