How many particles are contained in 25 mol of CO2 molecules?

To find the number of particles in 25 mol of CO2 molecules, we can use Avogadro's number, which is approximately 6.022 x 10^23 particles per mole.

Therefore, the number of particles in 25 mol of CO2 molecules would be:

25 mol x 6.022 x 10^23 particles/mol = 1.5055 x 10^25 particles

So, there are approximately 1.5055 x 10^25 particles in 25 mol of CO2 molecules.

1.505 x 10^25 particles
