In the chemical reaction below, AB decomposes to form A2 and B2. 2AB→ A2+B2

Using the above reaction, follow the steps listed below to calculate how many molecules of B2 are produced when 28.2 g of substance AB decomposes. The molar mass of substance AB is 16.9 g/mol.

Step 1: Convert the mass of AB to moles.

Step 2: Convert the number of moles of AB to the number of moles of B2.

Step 3: Convert the number of moles of B2 to molecules of B2.
