Answer: 143.3
137+115+104+263+98 divided by 5.Which gives us 143.3
The empirical formula : C₂Cl₇
The molecular formula : C₁₀Cl₃₅
<h3>Further explanation</h3>
Given
8.81 g Carbon
91.2 g Chlorine
Molar Mass: 1362.5 g/mol
Required
The empirical formula and molecular formula
Solution
Mol ratio :
C = 8.81 g : 12.011 g/mol =0.733
Cl = 91.2 g : 35,453 g/mol = 2..572
Divide by 0.733
C : Cl = 1 : 3.5 = 2 : 7
The empirical formula : C₂Cl₇
(The empirical formula)n = the molecular formula
(C₂Cl₇)n = 1362.5
(2x12.011+7x35.453)n=1362.5
(272.193)n=1362.5
n = 5
Molecules can share electrons, gain them, and lose them.
D=mass/volume
1st sample: D=41.40g/4.5mL
D=9.2 g/mL
2nd sample: D=37.22g/4.3mL
D=8.66 g/mL
3rd sample: D=43.46g/4.8mL
D=9.05 g/mL
Average Density: 9.2+8.66+9.05=26.91
Answer: 26.91/3=8.97 g/mL
Polarity is a term used in electricity, magnetism, and electronic signaling. Suppose there is a constant voltage , also called an electric potential or electromotive force (EMF), between two objects or points. In such a situation, one of the objects or points (poles) has more electrons than the other.
<h3>What causes electrical polarity?</h3>
This happens when the hot and neutral wires get flipped around at an outlet, or upstream from an outlet. Reversed polarity creates a potential shock hazard, but it's usually an easy repair.
<h3>Why is electrical polarity important?</h3>
When working with electrical circuits, we often refer to the polarity between different points in the circuit. Understanding polarity is important for connecting the leads of polarity-dependent devices such as some meters and motors. Polarity is also important for determining the direction of current flow.
