What is the mass of 0.7891 mol of ferric oxide (#Fe_2O_3#)?

Answer 1

#Fe_2O_3# has a formula mass of #159.69*g*mol^-1#.

Multiply the number of moles by the molar mass to obtain the mass of a particular molar quantity in grams:

#159.69*g*mol^-1xx0.7891*mol# #~=# #128*g#.

In ferric oxide, what is the iron's oxidation state?
