n (BaSO4) = 0.12 mol.
Determine the number of barium sulfate molecules. For this we use the following formula. We write down the solution.
N = Na × n.
Na = 6.02 × 10 ^ 23 molecules.
Where Na is Avogadro’s number.
n is the amount of substance.
N = 0.12 x 6.02 x 10 ^ 23 = 0.7224 x 10 ^ 23 = 7.224 x 10 ^ 22 molecules.
Hence, the number of molecules is 7.224 × 10 ^ 22.
Answer: N = 7.224 × 10 ^ 22 molecules.
