How many atoms are in 1.75 mol of CHCl3?
One mole is always equal to 6,0210²³ atoms of molecules, therefore:
1mol → 6,0210²³ atoms of molecules
1,75mol → x
x = 1,756,0210²³
x = 10,53510²³ or \(x \approx 1,05*10^{24} atoms\)
1 molecule de CHCl3 ------ 5 atoms (1C, 1H, 3Cl)
1,0510^24 -------------------- y
\(\boxed{y \approx 5,25*10^{24} atoms}\)
