Question

How many particles are there in 4 mol of Al?​

Answer 1

Answer:  2.41 × 10²⁴ particles

Explanation:

Number of particles = moles × Avogadro's Number

                                 =  4 mol  ×  (6.022 × 10²³) particles/mol

                                 = 2.41 × 10²⁴ particles

 ∴    the number particles in 4 mol of Al is 2.41 × 10²⁴ particles
