Answer:
9.0 x 10^23 CO2 molecules
Step-by-step explanation:
To calculate the number of CO2 molecules in 1.5 moles, we need to use Avogadro's number, which is the number of particles in one mole of a substance. Avogadro's number is approximately 6.02 x 10^23 particles per mole.
We can use this information to convert the number of moles to the number of molecules using the following equation:
number of molecules = number of moles x Avogadro's number
So, for 1.5 moles of CO2, the number of molecules would be:
number of molecules = 1.5 mol x 6.02 x 10^23 molecules/mol
number of molecules = 9.03 x 10^23 molecules
Therefore, there are approximately 9.03 x 10^23 CO2 molecules in 1.5 moles of CO2.
