Answer:

The answer to your questions is below

Explanation:

From the information given, we noticed that these compounds have similar properties that make us think that they are the same substance. But when we know that their density is different we discard this possibility.

But we can conclude that they are organic molecules with very similar structures whose only difference could be one carbon.

Vadim26 [7]

Volatile organic compounds can be detected by hydrogeologists in the field or labs because of the odor of the vapors emitted from the groundwater and/or soil samples.

<h3>What are volatile substances?</h3>

Volatile substances are substances which can easily vaporize or change to gaseous state.

Volatile substances can either be solids or liquids but are mostly liquids.

Example of volatile substances include ether, petrol, chocolate.

The presence of volatile substances can be detected by the gases they release which may have characteristic odors.

Therefore, volatile organic compounds can be detected by hydrogeologists in the field or labs because of the odor of the vapors emitted from the groundwater and/or soil samples.

<u>Atomic Structure</u>

  • Using Dimensional Analysis
  • STP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K
<h3>Explanation:</h3>

<u>Step 1: Define</u>

0.07 mol Ne (g)

<u>Step 2: Identify Conversions</u>

STP - 22.4 L per mole

<u>Step 3: Convert</u>

  1. Set up:                                \displaystyle 0.07 \ mol \ Ne(\frac{22.4 \ L \ Ne}{1 \ mol \ Ne})
  2. Multiply:                              \displaystyle 1.568 \ L \ Ne

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 1 sig fig.</em>

1.568 L Ne ≈ 2 L Ne
