How many silver atoms are there in 3.68 g of silver?
3.68 grams silver (1 mole Ag/107.9 grams)(6.022 X 10^23/1 mole Ag) = 2.05 X 10^22 atoms of silver -----------------------------------------
How many atoms are in .23 g Pb?
The number of atoms of lead is 6,68.10e23.
What mass of gold contains twice as many atoms as 2.74g of silver?
The gram atomic mass of silver is 107.868 and that of gold is 196.967. Equal numbers of gram atoms of different elements contain equal numbers of atoms. Therefore, the mass of gold required to contain twice as many atoms as 2.74 g of gold is (2 X 2.74 X 196.967)/107.868 or 10.0 g of gold, to the justified number of significant digits.
A sensitive balance can detect masses of 1 10-8 g How many atoms of silver would be in a sample having this mass?
1
How many atoms are in 149 g of calcium?
149 g of calcium contain 22,39.10e23 atoms.
How many silver atoms are there in g of silver?

How many dozens of silver atoms are in the piece of jewelry?
It depends on the weight of the silver in the material. 107.89 g of silver will have 6.023 x 1023 atoms of silver
How many silver atoms are there in 3.68 g of silver?
3.68 grams silver (1 mole Ag/107.9 grams)(6.022 X 10^23/1 mole Ag) = 2.05 X 10^22 atoms of silver -----------------------------------------
How many atoms are in .23 g Pb?
The number of atoms of lead is 6,68.10e23.
What mass of gold contains twice as many atoms as 2.74g of silver?
The gram atomic mass of silver is 107.868 and that of gold is 196.967. Equal numbers of gram atoms of different elements contain equal numbers of atoms. Therefore, the mass of gold required to contain twice as many atoms as 2.74 g of gold is (2 X 2.74 X 196.967)/107.868 or 10.0 g of gold, to the justified number of significant digits.
How many atoms are in 49.1740 g of zirconium?
49.1740 g (6.02 x 1023 atoms) / (91.22 g) = 3.25 x 1023 atoms
A sensitive balance can detect masses of 1 10-8 g How many atoms of silver would be in a sample having this mass?

How many atoms are in 149 g of calcium?
149 g of calcium contain 22,39.10e23 atoms.
How many atoms are in 38.260 g of chlorine?
6,687.1023 chlorine atoms
How many atoms are there in 63.5 g of carbon monoxide?
27,30.10e23 atoms
How many atoms are in g Pb?
The number of atoms of lead is 6,68.10e23.
How many atoms are there in 30.4 g of selenium?
78.96 g of selenium will have 6.023 x 1023 atoms. So, 30.4 g of selenium will have 2.32 x 1023 atoms.
