After calculating the molecular weight of CuBr2, we find that the atomic weight of Cu is 63.55 g/mol and the molecular weight of CuBr2 is 187.4 g/mol.
To find the percent of Cu in CuBr2, we perform the following calculation:
(63.55 g/mol / 187.4 g/mol) x 100% = 33.91%
Therefore, the percent of Cu in CuBr2 is approximately 33.91%.
What is the percent of Cu in CuBr2 ?
