Paper thickness varies. Typically, 100 sheets are about a cm thick. Atoms typically vary from 1 to 3 angstroms in radius. (An angstrom is 10-10 m.) Suppose a piece of paper is 0.0072 cm thick. How many atoms span the thickness if the radius of the atom is 1.23 angstroms

Explanation:

Thickness of a piece of paper = 0.0072 cm

Radius of an atom =

Conversion factor of to is

Diameter of an atom =

Number of atoms in one piece of paper is

Hence, the number of atoms in one piece of paper is .

sry but any answer choices

a gas, having a molecular weight of 13 kg/kmol and a kinematic viscosity of 0.25 cm2/s, flows through a pipe 0.25 m internal diameter and 5 km long at the rate of 0.4 m3/s and is delivered at atmospheric pressure.
