3.4 mole Cu (6.022 X 10^23/1mol Cu ) = 2.047 X 10^23 atoms of copper.
3,4 moles of CuSO4 contain 20,4752789138.10e23 molecules.
Approximately 2.05*10^24 molecules.
0,5 atom is a nonsense !
4,5 moles of copper are equivalent to 285,957 g.
Divide that number of atoms by 6.02x10^23 atoms/mole
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.
4.0 moles Cu (6.022 X 1023/1 mole Cu) = 2.4 X 1024 atoms of copper ====================
3.7x10^3 millimoles is 3.7 moles. To convert moles to atoms, multiply by avagadro's number. 3.7 x 6.022x10^23 is 2.22814x10^24 atoms.

3.7x10^3 millimoles is 3.7 moles. To convert moles to atoms, multiply by avagadro's number. 3.7 x 6.022x10^23 is 2.22814x10^24 atoms.
The formula for converting is: atoms ÷ Avogadro's constant = # moles (1.8 × 1023) ÷ (6.02 × 1023)= 0.299 moles Cu
When 3 moles Cu react 3 moles of copper nitrate are obtained.
The answer is 3 moles of Cu)NO3)2..
The molar mass of copper is its atomic weight on the periodic table in g/mol, and is 63.5g/mol We know that one mole of copper contains 6.022×10^23 atoms of copper . First convert given mass to moles, and moles to atoms. = 61.0 g Cu × (1 mol Cu / 63.5 g per mol) ×6.022 × 10 ^23 atom cu / 1 mol Cu) = 5.78× 10^23. atoms. 61 g Cu 5.7 ×10^23 atoms of Cu.
