[Ar] 3s^23p^6 since Ar is in period 3 and have all the orbitals filled with electrons
The correct answer is evaporation because Vaporization that takes place only on the surface of a liquid is called Evaporation.

Answer:
Empirical formula of 81.8 carbon and 18.2 hydrogen
Steps
- Find the empirical formula of a compound that has 81.8% of Carbon (C), 18.2% of Hydrogen (H).
- Divide by fractional component of each mole value: C=1.5354936431103, H=4.0709872862205Round to closest whole numbers: C=2, H=4
<h3> Combine to get the empirical formula: C2H4</h3>
Mass % of NaCl = 0.9 % (m/v)
Density of 0.9 % NaCl is about 1.0 g/mL
Volume of NaCl in mL :
= 11.25 mL NaCl
