What is the size of a molecule in scientific notation?

The size of a molecule typically ranges from about 1 to 100 nanometers in diameter. In scientific notation, this can be expressed as approximately (1 \times 10^{-9}) meters to (1 \times 10^{-7}) meters. For example, a typical small molecule like water has a molecular size on the order of (2.75 \times 10^{-10}) meters.
