2.11x10^24 atoms...
Divide by Avogadro's Constant (6.02x10^23 particles/mole)
Gives you moles of copper...
Multiply by the molar mass of copper. (?? g/mol)
Gives you grams of copper...

How many dozens of copper atoms in a penny?
A US 1 cent piece prior to 1982 was made of copper and had a mass of about 3.1g. This is about 0.049 moles of copper, or around 2.9 x 1022 atoms. More recent pennies are mostly zinc (97.5%) and have a mass of about 2.5g. This works out to around 2.2 x 1022 zinc atoms and 5.9 x 1020 copper atoms, so overall around 2.3 x 1022 atoms.
How many atoms are present in 6.81g of copper?
6.81 grams copper (1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 6.45 X 1022 atoms of copper ----------------------------------------
What is the mass of 19 atoms of copper in grams?
Not much! 19 atoms Cu (1 mole Cu/6.022 X 1023)(63.55 grams/1 mole Cu) = 2.0 X 10-21 grams of copper ---------------------------------------
How many copper atoms in a penny made of pure copper and weight 2.15g?
2.15 grams copper (1 mole Cu/63.55 grams)(6.022 X 10^23/1 mole Cu) = 2.04 X 10^22 atoms of copper ------------------------------------------
How many copper atoms are in a pure copper statue with a mass of 133 kg?
A lot! 154 kg copper (1000 grams/1 kg)(1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 1.46 X 1027 atoms of copper ---------------------------------------
How to convert grams to atoms?
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.
How many atoms of copper are there in 497.3 grams of copper?
The answer is 47,128 x 1023 atoms.

How many atoms of copper are there in a pure copper cion weighing 12.0 grams?
12.0 gram copper coin (1 mole Cu/63.55 grams)(6.022 X 10^23/1 mole Cu) = 1.14 X 10^23 atoms of copper
How many copper atoms are in a pure copper statue with a mass of 133 kg?
A lot! 154 kg copper (1000 grams/1 kg)(1 mole Cu/63.55 grams)(6.022 X 1023/1 mole Cu) = 1.46 X 1027 atoms of copper ---------------------------------------
How many copper atoms are in a pure copper statue with a mass of 129 kg?
The atomic weight of copper is 63.546 grams per mole. 129 kg is equal to 129000 grams. So there are 2030.03 moles of copper. There are 6.022 x 10^23 copper atoms in a mole. So there are 12.22 x 10^26 atoms.
How many atoms in 8 grams of copper?
Actually, it depends very much on how big your piece of copper is, but in just a small coin made of copper, you can actually find many billions or even trillions of atoms of copper. Extra fact: Atoms of elements are actually so small that their atomic radii are measured in pico meters (1pm=1x10-12m)
How do you convert 2.2 grams in to atoms in nitrogen?
14 grams of nitrogen have 6.023 x 1023 atoms So 2.2 grams will have (6.023 x 1023 x 2.2)/14 = 29.15 x 1023 atoms
