Answer:
17.46× 10²³ molecules
Explanation:
Given data:
Mass of acetic acid = 172.90 g
Number of molecules = ?
Solution:
First of all we will calculate the number of moles of acetic acid :
Number of moles = mass / molar mass
Number of moles = 172.90 g/ 60.1 g/ol
Number of moles = 2.9 mol
Now the given problem will solve by using Avogadro number.
The number 6.022 × 10²³ is called Avogadro number.
1 mole = 6.022 × 10²³ molecules
2.9 mol × 6.022 × 10²³ molecules / 1 mol
17.46× 10²³ molecules
Avogadro number:
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
Answer: 
Explanation:
The Chemical equation for the formation of rust is:
Iron + Water + Oxygen ----> Rust
4 Fe(s) + 6 H2O(l) + 3 O2(g) → 4 Fe(OH)3(s)
The Iron Hydroxide However dehydrates to produce Fe2O3 * nH2O
