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?\n102.0 g al₂o₃ / 1 mol al₂o₃\n1 mol al₂o₃ / 102.0 g al₂o₃\n1 mol al₂o₃ / 1 g al₂o₃\n102.0 mol al₂o₃ / 102.0 g al₂o₃

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?\n102.0 g al₂o₃ / 1 mol al₂o₃\n1 mol al₂o₃ / 102.0 g al₂o₃\n1 mol al₂o₃ / 1 g al₂o₃\n102.0 mol al₂o₃ / 102.0 g al₂o₃

Answer

Answer:

B. $\frac{1\ mol\ Al_2O_3}{102.0\ g\ Al_2O_3}$

Explanation:

Step1: Understand molar - mass conversion factor

The molar mass of $Al_2O_3$ is given as 102.0 g/mol. A conversion factor is a ratio that is used to convert between units. The normal molar - mass conversion factor is $\frac{102.0\ g\ Al_2O_3}{1\ mol\ Al_2O_3}$.

Step2: Find the inverted conversion factor

To get the inverted conversion factor, we simply flip the ratio. So the inverted conversion factor of the molar mass of $Al_2O_3$ is $\frac{1\ mol\ Al_2O_3}{102.0\ g\ Al_2O_3}$.
