The molar mass of iron oxide (Fe2O3) is 159
g/mol. What is the correct way to write the molar
mass of iron oxide as a conversion factor?
159.7 g Fe, O
159.7 mol Fe, og
1 g Fe, og
159.7 mol Fe, O
159.7 g Fe,
1 mol Fe20
1 g Fe,
1 mol Fe,

i would say b

explanation:

but i think i would need more information than that

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.

i think its 5049.

i hope this !
