CaF2 = Calcium fluoride (leave it as is, it in emoerical form already)
Na20 = Sodium oxide (leave it as is, it in emoerical form already)
BaS = Barium Sulfide (leave it as is, it in emoerical form already)
CuSO4 = Copper(II) sulfate = CuSO4 5H2O
Fe2O3 = Iron(III) oxide (leave it as is, it in emoerical form already)
HgCl2 = Mercury(II) chloride (leave it as is, it in emoerical form already)
KC2H3O2 = Potassium Acetate (leave it as is, it in emoerical form already)
Al(OH)3 = Aluminium hydroxide (leave it as is, it in emoerical form already)
Fe(NO3)3 = Iron(III) nitrate (leave it as is, it in emoerical form already)
N2O5 = Dinitrogen pentoxide = N2O5 (it's subscrip is already simplified)
PO5 = Phosphorus pentoxide = P2 O5 (there was just no 2 after the P so that's all that was needed there)
I'm am so sorry if this didn't help too much, I hope I did help, I in some way, have a wonderful day.
Answer:
3.29 × 10²⁸ Atoms
Solution:
Moles and Number of atoms are related to each other as,
Moles = Number of Atoms / 6.022 × 10²³ ------- (1)
Data Given;
Moles = 5.472 ×10⁴
Number of Atoms = ?
Solving eq. 1 for Number of Atoms,
Number of Atoms = Moles × 6.022 × 10²³
Putting values,
Number of Atoms = 5.472 ×10⁴ mol × 6.022 × 10²³ atoms.mol⁻¹
Number of Atoms = 3.29 × 10²⁸ Atoms
by classifying into categories that get smaller and smaller these are the classification steps : life , domain , kingdom , phylum , class, order , family , genus , and species every time you narrow it down the option gets smaller and smaller till there's none left except the species it self .
I hope it helps you ❤️❤️❤️❤️
