Your answer to this question is 1.20 times 1024 atoms
Answer:
C = 9460 Kj
Explanation:
Given data:
Mass of copper = 2kg
Latent heat of vaporization = 4730 Kj/Kg
Energy required to vaporize 2kg copper = ?
Solution:
Equation
Q= mLvap
by putting values,
Q= 2kg × 4730 Kj/Kg
Q = 9460 Kj
This is Bohrs model for potassium
The formula of butane is C4H10 but I don't how many atoms it contains though
