Propene has three electron groups surrounding the core carbon atom, as seen in the Lewis dot structure of the compound.
<h3>What is Lewis dot structure?</h3>
A Lewis Structure is a greatly condensed illustration of a molecule's valence shell electrons. It is used to display how the electrons are positioned around particular molecules' atoms. When two atoms are bonded together, electrons are depicted as "dots" or as a line.
Lewis structures, often referred to as Lewis dot formulas, electron dot structures, or Lewis electron dot structures, are diagrams that depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

Answer:
Moles = 0.271 mol
Solution:
Step 1: Calculate Mass of Br₂ as;
Density = Mass ÷ Volume
Solving for Mass,
Mass = Density × Volume
Putting values,
Mass = 3.12 g.mL⁻¹ × 13.9 mL
Mass = 43.36 g
Step 2: Calculate Moles of Br₂ as;
Moles = Mass ÷ M.Mass
Putting values,
Moles = 43.36 g ÷ 159.80 g.mol⁻¹
Moles = 0.271 mol
Answer:
3.79 grams
Explanation:
22.4= STP volume . Molar mass of NH3=17.031
5.00 NH3 × (1 mol/22.4 L) =0.223
convert to grams->
0.223× 17.031= 3.79
