One problem with organic chemistry is that we tend to focus on one molecule at a time, we forget that there are many, many molecules undergoing the reaction. Assume you started with exactly 1 g of bromobenzene, how many MOLECULES OF bromobenzene is this?

Answer:

1g of bromobenzene = 3.84× 10^21 molecules

Explanation:

Molar mass of bromobenzene (C6H5Br)= 79.9+(12×6)+ 5= 156.9

156.9g(1mole) has 6.023×10^23 molecules

This implies that 1g will contain 6.023×10^23/156.9 = 3.84×10^21 molecules
