Please with explanations since I am misunderstanding about it.
Calculate the number of particles in
1.) 2.50 moles of neon, Ne
2.) 0.050 moles of irons, Fe
Calculate the number of moles in
1.) 9.03*10^23 atoms of Cu
2.) 3.76*10^25 molecules of SO2
3.) 8.6 *10^18 electrons
Chem : Mole concept (Part 2). Extremely urgent!

✔ 最佳答案
1) the no. of particles :2.50 * 10^23
2) the no. of particles :
0.050 * 10^23
No. of moles * 6.02* 10^23 = no. of particles
1) the number of moles:
9.03 * 10^23 / 10^23
=9.03 mol
2) the number of moles:
(3.76 * 10^25 )/ (10^23 / 3)
because 1 SO2 contains 3 atoms
3 ) the number of moles:
8.6 * 10^18 / 10^23
