Molecular distances are usually given in nanometers (1 nm = 1 × 10-9 m) or in picometers (1 pm = 1 × 10-12 m). However, the angstrom (Å) unit is sometimes used, where 1 Å = 1 × 10-10 m. (The angstrom unit is not an SI unit.) If the distance between the Pt atom and the N atom in the cancer chemotherapy drug cisplatin is 1.97 Å, what is this distance in nanometers? In picometers?
