Work out the volume of the coin first. Then using density formula, mass of this coin can be calculated. From mass find the number of moles. Then Avogadro's number will take care of the rest.

Estimate the number of gold atoms in a gold coin with a diameter of 1 cm and a thickness of 1mm?

A gold coin with a diameter of 1 centimeter and a 1 mm thickness has a volume of .07854 cubic centimeters. Gold has a density of 19.30 grams per cubic centimeter. There is 1.5158 grams of gold or 7.7 millimoles or 4.637 E21 atoms.


How do you find the thickness of a molecule?

we dont find thickness of molecule we find the radius of it vander waal radius for gases. first of all we take a beaker (all dimension are known), then we inject molecules of substance but a uniform flow and with the use of atomizer these atoms or molecules settle down on the bottom of beaker layer by layer when we get full bottom covered with molecules then we find thickness of the layer and estimate no. of atoms in layer with the help of different methods and the we divide it with estimated no. of atoms this way we find the diameter of atoms or molecule then we just divide it by 2. more precisely scientist take extreme precautions while performing the above experiments.

How many chromium atoms would have to be lined up to Span 1.0cm if the diameter is 2.2 A?

One Angstrom is defined as 10-10 centimeters. Therefore, the number of any units with a diameter of 2.2 Angstroms that would be required to span 1.0 cm is 1.0/10 -10 or 4.5 X 109 calcium atoms., to the justifiable number of significant digits.

How many atoms are in 1.62 moles Nickel?

The definition of one mole is: It is a number (eg. of particles of any kind), like pi is a number (of ratio from diameter to circle).It is a very big number, symbolised as NA (and named after Avogadro):NA = 6.022 * 1023 (-/mol) or (mol-1)So there are 1.62 * NA = 9.76 * 1023 atoms in a mole(it is not important of what kind the atoms are).
