Avogadro's Number Chemistry Example 1

Solution

1. 1
   Convert moles to particles with Avogadro's number: $N = n \times N_A$.
2. 2
   Substitute the values: $N = 2.5 \times 6.022 \times 10^{23}$.
3. 3
   Multiply to get $N = 1.506 \times 10^{24}$ molecules, which rounds to $1.51 \times 10^{24}$ molecules.
