The number of molecules in a mole is known as Avogadro's number, which is approximately 6.022 x 10^23.

To calculate the number of molecules in 0.5 moles of CO, you would multiply the number of moles by Avogadro's number:

0.5 moles * 6.022 x 10^23 molecules/mole = 3.011 x 10^23 molecules

So, the correct answer is a) 3.011x10^23.
