The molar mass of aluminum oxide (Al2O3) is 102.0 g/mol. What is the correct way to write the inverted molar mass of aluminum oxide as a conversion factor?

Let us assume that fe (oh) 2 (s) is completely insoluble, which signifies that the precipitation reaction with naoh (aq) (presented in the transition) would go to completion. fe2 + (aq) + 2naoh (aq) → fe (oh) 2 (s) + 2na + (aq) if you had a 0.
