How many atoms are in 1.75 mol of CHCl3?
One mole is always equal to 6,02*10²³ atoms of molecules, therefore:
1mol → 6,02*10²³ atoms of molecules
1,75mol → x
x = 1,75*6,02*10²³
x = 10,535*10²³ or [tex]x \approx 1,05*10^{24} atoms [/tex]
1 molecule de CHCl3 ------ 5 atoms (1C, 1H, 3Cl)
1,05*10^24 -------------------- y
[tex]\boxed{y \approx 5,25*10^{24} atoms}[/tex]
