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 ----------------------------------------
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 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 would be found in 1.2 grams of copper?
1.2 g Cu * (1 mole Cu / 63.54 g Cu)*(6.022x1023 atoms Cu / mole Cu)1.137x1022 atoms of copper
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 many grams of copper could you get from 30 grams of aluminum?
None, as pure Aluminium is an element which contains only atoms of Aluminium and nothing else.
How many atoms are there in a copper and what are they?
Copper is an element. You can have a single atom or many atoms and it's still copper.
How many atoms present in 1 cubic centimeter of copper with a density of 8.96g cm3?
From the density and volume, the mass of this amount of copper is 8.96 grams. There are 63.546 grams in 1 mole of copper, so this is 0.141 moles. There are 6.023 x 10²³ atoms in 1 mole. Multiply this by 0.141 moles = 8.492 x 10²² atoms.
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 moles of atoms are in 4.5 grams of Cu?
4,5 moles of copper are equivalent to 285,957 g.
