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?
102.0 g Al2O3
1 mol Al2O3
1 mol Al2O3
102.0 g A1,02
1 mol Al02
1 9 AIRO,
102.0 mol Al2O3

Answer:

[tex]\frac{1molAl_2O_3}{102.0gAl_2O_3}[/tex]

Explanation:

Hello,

In this case, as the molar mass means that 1 mole of a substance has an specific amount of grams of the same substance, for aluminium oxide, we see that in one mole, there are 102.0 grams of it, which is symbolized by:

[tex]\frac{102.0gAl_2O_3}{1molAl_2O_3}[/tex]

Nonetheless, the inverted molar mass, which is useful to compute the moles of aluminium oxide when mass is given is defined as:

[tex]\frac{1molAl_2O_3}{102.0gAl_2O_3}[/tex]

Which has now moles above and grams below.

Best regards.
