Comparison of the Number of Particles in 2.5 Moles of Oxygen and Lead

To compare the number of particles in 2.5 moles of oxygen and lead, we need to consider Avogadro's number, which is approximately 6.022 x 10^23 particles per mole. This number represents the number of atoms, molecules, or ions in one mole of a substance.

Let's calculate the number of particles in 2.5 moles of oxygen and lead:

1. Oxygen (O2): - Avogadro's number tells us that there are approximately 6.022 x 10^23 particles in one mole of oxygen. - Therefore, in 2.5 moles of oxygen, the number of particles can be calculated as follows: ``` Number of particles = 2.5 moles * (6.022 x 10^23 particles/mole) = 1.5055 x 10^24 particles ``` - So, there are approximately 1.5055 x 10^24 particles in 2.5 moles of oxygen.

2. Lead (Pb): - Similarly, we can calculate the number of particles in 2.5 moles of lead. - However, we need to consider the molar mass of lead, which is approximately 207.2 grams/mole. - The molar mass allows us to convert the number of moles of lead into grams. - Then, using the molar mass and Avogadro's number, we can calculate the number of particles. - The calculation is as follows: ``` Number of particles = 2.5 moles * (6.022 x 10^23 particles/mole) = 1.5055 x 10^24 particles ``` - Therefore, there are approximately 1.5055 x 10^24 particles in 2.5 moles of lead.

In conclusion, both 2.5 moles of oxygen and lead contain approximately 1.5055 x 10^24 particles.
