How many atoms are in each elemental sample 4.0mol Cu?
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 atoms of copper ====================
How many moles of Cu are in the 148 times 10 to the power 25 atoms?
15.8 moles Cu x 6.02x10^23 atoms/mole = 9.51x10^22 atoms. There are no molecules in the element Cu (copper). Molecules are found when there are two or more atoms bound together, such as in H2 gas or H2O, etc.
How many moles are of Cu are there in 3.0x1021 atoms?
The formula unit for copper is a single atom. Avogadro's Number is the number of atoms, formula units, or molecules per mole. (3.0 X 1021)/(6.022 X 1023) equals 5.0 X 10-3 moles, to the justified number of significant digits.
How many. atoms. are present in 2.5 moles?
For this you do not have to have an Atomic Mass. Take the number of moles and multiply it by Avogadro's constant, 6.02 × 1023. Divide by one mole for units to cancel.2.5 moles × (6.02 × 1023 atoms) = 1.51 × 1024atoms in 2.5 moles
How many grams do 4.6 x1025 atoms of cu weigh?
I assume you mean 4.6 X 10^25 atoms. This is the conversion. 4.6 X 10^25 atoms Cu ( 1mol Cu/ 6.022 X 10^23 )( 63.55 grams Cu/ 1 mol Cu ) = 4854.37 grams Cu
How many atoms are in each elemental sample 4.0mol Cu?
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 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 atoms are in 0.75 moles of neptunium?
6.02 X 1023 particles per mole X .75 moles = 4.52 X 1023 molecules.
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 ----------------------------------------
If you have 1.8 x 10 to the 23 atoms of copper how many moles of copper do you have?
The formula for converting is: atoms ÷ Avogadro's constant = # moles (1.8 × 1023) ÷ (6.02 × 1023)= 0.299 moles Cu
How many atoms are present in 3.14g of Cu?
3.14 g Cu = # atomsTake the known mass of copper multiply it by Avogadro number and divided by the atomic weight.Atomic weight of copper:63.5 g3.14 g Cu (6.02 × 1023 atoms) / (63.5 grams) = 2.98 × 1022 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 nitrogen atoms are in 10.2 g of copper(II) nitrate?
A mole of any element contains 6.022*1023 (Avogadro's Number) atoms of that element. So a mole of copper would contain 6.022*1023 atoms of copper.
How many moles of Cu are in the 148 times 10 to the power 25 atoms?
15.8 moles Cu x 6.02x10^23 atoms/mole = 9.51x10^22 atoms. There are no molecules in the element Cu (copper). Molecules are found when there are two or more atoms bound together, such as in H2 gas or H2O, etc.

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
