In one mole of a substance there are 6.0221415 x 1023 atoms.
here we have 1.75 moles, so there will be 6.0221415 x 1023 x 1.75 molecules in this amount of gold.
That will be 10.5387476 x 1023
How many moles of atoms are contained in 382 g Co
6.00 moles
2.26*1024
NH3 is balanced at 1:3, so in 3 moles NH3 there are 3*3 = 9 moles H atoms
2.36 moles x 6.022*10^23 atoms/mole. Moles cancel and you are left with 1.42*10^24 xenon atoms.
How many moles of atoms are contained in 382 g Co
5,26 moles of oxygen contain 31,676.10e23 atoms.
Two moles of neon contain 12,044281714.10e23 atoms.

12,4439 kg of gold contain 63,177 moles.
2.26*1024
NH3 is balanced at 1:3, so in 3 moles NH3 there are 3*3 = 9 moles H atoms
382 g Co contain 6,482 moles.
2.36 moles x 6.022*10^23 atoms/mole. Moles cancel and you are left with 1.42*10^24 xenon atoms.
4.2 X 10^24 atoms of gold / 6.022 X 10^23 atoms per mol) = 7.0 moles of gold
The number of phosphorus atoms is 63,181.10e23.
