The molar mass of iron oxide (fe2o3) is 159.7 g/mol. what is the correct way to write the molar mass of iron oxide as a conversion factor?

or

Explanation: Given molar mass of Iron(III)oxide is 159.7 g/mol. It means the mass of 1 mol of Iron(III)oxide is 159.7 g.

How to write the molar mass as a conversion factor is all depends if we are calculating the moles or grams.

If the grams are given and we are asked to calculate the moles then the conversion factor is written as and if the moles are given and we are asked to calculate the grams then the conversion factor is written as .

c 159.7g Fe2 O3/ 1 mol Fe2 O 3

Explanation:

I just did it:)

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
