Final answer:
To find the number of particles in 0.02993 mol of K₂S, multiply the number of moles by Avogadro's number.
Step-by-step explanation:
To find the number of particles in 0.02993 mol of K₂S, we need to use Avogadro's number. Avogadro's number gives us the number of particles (atoms, ions, or molecules) in one mole of a substance. Avogadro's number is approximately 6.022 × 1023 particles/mol.
In this case, we have 0.02993 mol of K₂S. To find the number of particles, we can multiply the number of moles by Avogadro's number: 0.02993 mol × 6.022 × 1023 particles/mol = 1.8 × 1022 particles.
