How may atoms of oxygen are present in Cu(NO3)2?
Copper(II) nitrate has six oxygen atoms.
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 moles of atoms are in 450000000000000000000000 atoms of Cu?
Divide that number of atoms by 6.02x10^23 atoms/mole
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 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 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 Cu atoms are present in a piece of sterling-silver jewelry weighing 33.14 g?
This depends on the percentage of copper in the alloy.If this alloy contain 7,5 % Cu the number of copper atoms is approx. 0,2355.10.e+23.
How may atoms of oxygen are present in Cu(NO3)2?
Copper(II) nitrate has six oxygen atoms.
How many atoms are in CuNO3 2?
Cu(NO3)2 has 9 atoms 1 Cu atom 2 N atoms 6 O atoms
How many atoms of copper Cu are in a pure copper coin weighing 12.0 g?
Answer: 1.14x10^23 atoms Cu (12.0g Cu/63.55amu(g) Cu) Then take (Ans x 6.022x10^23) = 1.13712038x10^23 atoms Cu. Then I simplified it to 3 sig figs. = 1.14x10^23 atoms Cu Never forget your units and substance!
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 oxygen atoms are present in a 14.0 g sample of Cu(NO3)2?
14.0 g x 1 mole/187.56 g = 0.0746 moles0.0746 moles Cu(NO3)2 x 6 moles O/mole Cu(NO3)2 = 0.448 moles O atoms0.448 moles O atoms x 6.02x10^23 atoms/mole = 2.70x10^23 atoms of oxygen
How many moles of atoms are in 450000000000000000000000 atoms of Cu?
Divide that number of atoms by 6.02x10^23 atoms/mole
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 atoms are in 1 mole of Copper?
1 mol Cu Atoms (6.02x10^23 atoms)
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.
