Answer:

Molar mass of hematite#159.6922g.mol^-1#

Explanation:

Molecular formula of hematite is iron(III) oxide, #"Fe"_2"O"_3#.
Average atomic mass of iron is #55.847#
Average atomic mass of oxygen is #15.9994#
Mass of one Molecule of hematite#=2xx55.847+3xx15.9994#
#=159.6922#
Molar mass of hematite#159.6922g.mol^-1#
