Please answer a through e

In a chemical reaction, exactly 2 mol of substance A react to produce exactly 3 mol of substance B.

2A --> 3B

How many molecules of substance B are produced when 28.0 g of substance A reacts? The molar mass of substance A is 24.4 g/mol.

Step 1: Convert the mass of A to moles.

Step 2: Convert the number of moles of A to the number of moles of B.

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

(If you can, besides answering the question, please explain if possible. thank you so much!)
