Answer:
The answer to your question is 4.07 x 10²² atoms
Explanation:
Process
1.- Get the molecular weight of Cocaine hydrochloride
C = 12 x 17 = 204 g
H = 22 x 1 = 22 g
Cl = 36 x 1 = 36 g
N = 14 x 1 = 14 g
O = 16 x 4 = 64 g
Molecular mass = 340 g
2.- Calculate the moles of the mass given
340 g ------------------- 1 mol
23 g ------------------- x
x = (23 x 1) / 340
x = 0.068 moles of Cocaine
3.- Calculate the atoms
1 mol -------------------- 6 .023 x 10 ²³ atoms
0.068 moles ------------- x
x = (0.068 x 6.023 x 10²³) / 1
x = 4.07 x 10²² atoms
