1) Calculate the number of C atoms in 0.334 mole of C. Nc=______atoms of C
2) Calculate the number of SO2 molecules in 2.73 moles of SO2. NSO2=______ molecules of SO2
3) Calculate the moles of Fe in 2.82x1022 atoms of Fe. Nfe=_______ mole of Fe
4) Calculate the moles of C2H6O in 3.11x1024 molecules of C2H6O. nC2H6O=_______ moles of C2H6O
1)
use:
number of atoms = number of moles * Avogadro’s number
= 0.334 * 6.022*10^23 atoms
= 2.011*10^23 atoms
Answer: 2.01*10^23 atoms
2)
use:
number of molecules = number of mol * Avogadro’s number
number of molecules = 2.73 * 6.022*10^23 molecules
number of molecules = 1.644*10^24 molecules
Answer: 1.64*10^24 molecules
3)
use:
number of mol = number of atoms / Avogadro’s number
number of mol = 2.82*10^22 / 6.022*10^23 mol
number of mol = 4.683*10^-2 mol
Answer: 4.68*10^-2 mol
4)
use:
number of mol = number of molecules / Avogadro’s number
number of mol = 3.11*10^24 / 6.022*10^23 mol
number of mol = 5.164 mol
Answer: 5.16 mol
