How many atoms must be placed end-to-end to make a chain of atoms one-millionth meter long?
An atom is about 10-11 meter in diameter, so to make a chain of them 10-6 meter long you would need about 10-6/10-11 =105 or 100,000 atoms.
If a mole of atoms were spread uniformly over the surface of the Earth how many atoms would there be per square meter?
A mole of any substance contains 6.02x1023 atoms. The surface of the earth is about 510x106 km2. This surface area is the same as 5.10x1014 m2. Therefore each square meter would have (6.02x1023 atoms)/(5.10x1014 m2) atoms/m2. This reduces to 1.18x109 atoms/m2
What is smaller a molecule or a micron?
The units are incompatible. Millimetres are linear, micro-litres are for volume.
How many atoms are in one metre?
One meter does not have a fixed number of atoms since it is a measurement of length, not quantity. The number of atoms in one meter would vary based on the substance or material being considered.
Calculate the number of atoms per cubic meter in lead?
The number of atoms per cubic meter in lead can be calculated based on its density and atomic mass. Lead has a density of 11,343 kg/m^3 and an atomic mass of 207.2 g/mol. Using Avogadro's number, you can calculate that there are approximately 1.03 x 10^29 lead atoms in one cubic meter of lead.
What has a diameter of about one ten-thousand-millionth of a meter?
atoms
