The atomic radii of an Au atom is 174 pm. A pico meter is 10^-12 of a meter. Use this to easily convert to mm. Then multiply this value by two to find the diameter of one Au atom in mm. Finally, divide 1.5 by this answer to find the total Au atoms to span. You should get approximately 4.45 x 10^7 Au atoms.

How many gold atoms would have to be lined up to span 4.0 mm?
The radius of gold is 144 picometers, so....,144 picometers (103/1012)= 1.44 X 10 -7 mm------------------------so,4.0 mm/1.44 X 10 -7 mm= 2.8 X 107 * 2 ( because you need to double radius to get diameter end to end )= 5.6 X 107 gold atoms lined up======================
How many Carbon atoms would it take to make a inch?
It would take about 254 billion Carbon atoms lined up in a single row to span one inch.
How many atoms of gold are in the bar?
The number of atoms in a bar of gold depends on the mass of the bar. To calculate the number of atoms, you would need to know the mass of the bar and the atomic mass of gold. You can use Avogadro's number to convert from grams to atoms.
How many gold atoms does a drop of sea water contain?
There are roughly 8.3 x 10^22 atoms in a drop of seawater, but only a very small portion of these would be gold atoms. Gold is present in seawater in very trace amounts, estimated to be around 0.0000000004 mg of gold per liter of seawater, so the number of actual gold atoms would be miniscule compared to the total number of atoms in the drop.
How many atoms of gold were recovered in 197kg of gold?
To calculate the number of atoms in 197 kg of gold, you would first convert the mass of gold to moles using the molar mass of gold, which is approximately 197 g/mol. Then, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to find the number of atoms in the moles of gold.

If there is one sulphate molcule, there will be 2 gold atoms.
How many number of atoms is in 3.50g gold?
The formula unit for gold is a single atom, and the atomic weight of gold is about 197. Therefore, the number of atoms in 3.50 g of gold is Avogadro's Number X (3.50/197) or about 1.84 X 1022.

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.
