Surface over which the air mass was formed.
Answer:
CH₂
Explanation:
From the question given above, the following data were obtained:
Mass of compound = 1 g
Mass of CO₂ = 3.14 g
Mass of H₂O = 1.29 g
Empirical formula =?
Next, we shall determine the mass of Carbon and hydrogen present in the compound. This can be obtained as follow:
For Carbon, C:
Mass of CO₂ = 3.14 g
Molar mass of CO₂ = 12 + (2×16)
= 12 + 32
= 44 g/mol
Molar mass of C = 12 g/mol
Mass of C =?
Mass of C = molar mass of C/ Molar mass of CO₂ × Mass of CO₂
Mass of C = 12/44 × 3.14
Mass of C = 0.86 g
For hydrogen, H:
Mass of C = 0.86 g
Mass of compound = 1 g
Mass of H =?
Mass of H = (Mass of compound) – (mass of C)
Mass of H = 1 – 0.86
Mass of H = 0.14 g
Finally, we shall determine the empirical formula of the cyclopropane. This can be obtained as follow:
Mass of C = 0.86 g
Mass of H = 0.14 g
Divide by their molar mass
C = 0.86 / 12 = 0.07
H = 0.14 / 1 = 0.14
Divide by the smallest
C = 0.07 / 0.07 = 1
H = 0.14 / 0.07 = 2
Thus, the empirical formula of cyclopropane is CH₂
1.) protons neutrons and electrons
2.) a wall outlet it is made up of metal that conducts heat. When when heat is applied it provides enough energy to these electrons
3.) is an imbalance if electric charges within or on the surface of a material
4.) static electricity decoded tiny changes in the surface of a balloon causes it to charge more when rubbed against our hair
5.) you might have to answer that on your own but if you don’t want to here’s my experience
One day me and my twin brother were jumping on the trampoline and when we fell down my hair rubbed against the surface of it and stuck up

Answer:
3.4moles
Explanation:
Given parameters:
Number of molecules = 2.04 x 10²⁴
Unknown: Number of moles
Solution
We use the concept of mole to solve this kind of problem.
A mole is the amount of substance that contains Avogadro's number of particle i.e 6.02 x 10²³ molecules
Solving
For elementary particles:
Number of moles = 
¹ molecules
Number of moles = 
Number of moles of H₂O = 0.34 x 10¹ = 3.4moles
