A manufacturer makes a conductive ink that contains small particles of carbon. The manufacturer measures the diameter of one carbon particle in the ink as 18 nm18\ \text{nm}18 nm. The diameter of each carbon atom in the particle is 0.14 nm0.14\ \text{nm}0.14 nm.
Calculate the factor by which the diameter of the carbon particle exceeds the diameter of a carbon atom.
Give your answer to 2 significant figures.
The manufacturer's quality records list particle sizes in metres.
Give the diameter of the carbon particle in standard form.
