In a chemical reaction, exactly 2 mol of substance A react to produce exactly 3 mol of substance B.
How many molecules of substance B are produced when 26.5 g of substance A reacts? The molar mass of substance A is 21.9 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.

So what is your problem? The directins are there. The equation is
2A ==> 3B
To convert grams to mols remember mols = grams/molar mass.
To convert mols to molecules remember 1 mol of anything contains 6.02E23 of those "anythings".
