Silver (Ag) has a molar mass of 107.87g/mol, so by dividing 20.5 by its molar mass, you get how many moles of silver atoms there are in that much silver.
(20.5gAg)(1mol/107.87g) = 0.190 moles silver atoms
Now, 1 mole = 6.02*1023 (Like a dozen = 12, a mole is just a value.) so if you can't answer in moles, just multiply 0.190 moles by 6.02*1023
0.190 mol*(6.02*1023/1mol)= 1.14*1023 silver atoms

How many silver atoms are there in 3.70g of silver?
2.09*10^22 This is how you figure it out: 3.74g divided by 107.87(the atomic mass of silver). Then you multiply the number you get by 6.022x10^23 (Avogadros number). And that's your answer.
How many silver atoms are there in 3.88 g of silver?
2.17*10^22
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 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 silver atoms are there in 3.70g of silver?
2.09*10^22 This is how you figure it out: 3.74g divided by 107.87(the atomic mass of silver). Then you multiply the number you get by 6.022x10^23 (Avogadros number). And that's your answer.

Does 23 g of sodium and 238 g of uranium have equal number of atoms in them?
dose 23 grams of sodium and 238 grams of uranium have equal number of atoms in them
What mass of He contains the same number of atoms as 5.0 g Kr?
0.24 g
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.
