Answer:
CuSO4
element. quantity average
atomic mass
Cu. 1. x 64. = 64g/mol
S. 1. x 32. = 32g/mol
O. 4. x. 16. = 64g/mol
molecular mass. => 160 g/mo
there is a slight difference in answer because I round off the atomic mass of the elements.
KMnO4
K. 1 x 39. = 39 g/mol
Mn. 1 x 55 = 55 g/mol
O O x 16 = 64 g/mol
molecular mass. => 158 g/mol
