5.0 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au)
= 1.5 X 1022 atoms of gold
===================
5.0 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au)
= 1.5 X 1022 atoms of gold
===================
One mole of gold will contain 6.02 E23 atoms, per Avogadro's number. This means that 5.8 E24 atoms is equal to 9.635 moles.
With a molar mass of 196.96655 grams per mole, there are .0254 moles of gold present. Conversion with Avogadro's constant shows there are 1.53 E22 atoms of gold.
i do know how many atom are in 5 moles of gold
5.00 grams gold (1 mole Au/197.0 grams)(6.022 X 1023/1 mole Au)
= 1.53 X 1022 atoms of gold
==================
34 atoms
0,39 moles of gallium contain 2,34863493423.10e23 atoms.
Gold has a molar mass of 196.96655 grams per mole. 100 grams then is equal to .508 moles which makes 3.059 E23 atoms of gold.
20.4 MOLES OF PCl3
One mole of atoms is 6.02x1023 atoms, so 10 moles of any substance would contain 6.02x1024 atoms.
3 moles of Zn is equal to 18.09x1023 atoms. I used Avogadro's Number : 6.03x1023 particles/mol This number is the number of atoms or molecules in a mol of any substance. 3 moles X 6.03x1023 particles/mol = 18.09x1023 atoms
