You need to know what elements the coin is made up of (ie. what percent is iron and what percent is copper). You'd then need to weigh the coin out. If you wanted to know how many iron atoms there are, then you'd calculate how much iron there is and convert that to moles and then to atoms using avogadro's number.

What an Atoms identity?
The number of protons in the nucleus of the atom determine its identity.
How many total atoms are in Sq2R3?
To determine the total number of atoms in the chemical formula Sq2R3, you need to consider the subscripts. The formula indicates there are 2 atoms of element Sq and 3 atoms of element R. Therefore, the total number of atoms is 2 (from Sq) + 3 (from R) = 5 atoms.
How many atoms in 19.3 grams of gold on a sheet that is 0.00010?
To calculate the number of atoms in 19.3 grams of gold, you need to first determine the number of moles of gold. Then, you can use Avogadro's number (6.022 x 10^23) to find the number of atoms. Given that the sheet is only 0.00010 cm thick and the density of gold is 19.3 g/cm^3, you can determine the area of the sheet and then calculate the number of atoms.
How do you determine the number of atoms in CaCO3?
To determine the number of atoms in CaCO3, you would first calculate the molar mass of CaCO3 (40.08 g/mol + 12.01 g/mol + 3(16.00 g/mol)). Then, you would divide the given mass of CaCO3 by the molar mass to find the number of moles. Finally, you would use Avogadro's number (6.022 x 10^23 atoms/mol) to convert moles to the number of atoms in CaCO3.
Which of the atoms in the table are atoms of the same element?
To determine which atoms in a table are of the same element, you would look for atoms that have the same atomic number, as this identifies the element. Atoms of the same element will also have the same number of protons in their nucleus. If isotopes of an element are present, they will have the same atomic number but different mass numbers due to varying numbers of neutrons.
How can you determine an atoms identity?
By the number of protons it has.
How do you determine the numbers of atoms in a chemical equation?
It is necessary to balance the number of atoms for reactantas and products.

How does oxidation numbers determine the number of atoms?
Oxidation numbers indicate the charge of an atom in a compound. By comparing the oxidation numbers of different atoms in a compound and knowing their charges, you can determine the number of atoms involved in the reaction or compound. These numbers help balance chemical equations and determine the stoichiometry of a reaction.
What an Atoms identity?
The number of protons in the nucleus of the atom determine its identity.
What is the answer. Determine the number of atoms in 3.29 mol Zn?
To determine the number of atoms in 3.29 mol of Zn, you would use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Multiply the number of moles (3.29 mol) by Avogadro's number to find the number of atoms. The calculation would be: 3.29 mol Zn x 6.022 x 10^23 atoms/mol = 1.98 x 10^24 atoms of Zn.
What does the number of atoms in the nucleus determine?
Do you mean number of protons in a nucleus? The nucleus is part of an atom.
How many atoms of carbon are present in the reactants?
To determine the number of carbon atoms in the reactants, you need to specify which reactants you are referring to. The number of carbon atoms can vary depending on the chemical equation.
How many atoms are present in 80.0 mol of zirconium?
To determine the number of atoms in 80.0 mol of zirconium, you can use Avogadro's number, which is 6.022 x 10^23 atoms/mol. Multiply 80.0 mol by Avogadro's number to find the total number of atoms in 80.0 mol of zirconium.
How many grams atoms of sulfur are there in g of sulfur?
To determine the number of grams atoms of sulfur in a given mass of sulfur (g), you need to calculate the number of moles of sulfur first. Then, you can use Avogadro's number to convert moles to atoms. Finally, multiply the number of moles by Avogadro's number to find the number of atoms.
How many atoms does a gold coin have?
Let us assume this is a pure gold coin of the standard one ounce in weight. 1 ounce gold (1 lb/16 oz)(454 grams/1 lb)(1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au) = 8.67 X 1022 atoms of gold in a one ounce coin -------------------------------------------------------------
Estimate the number of gold atoms in a gold coin with a diameter of 1 cm and a thickness of 1mm?
