The mole fraction of the solute is given as 0.3019

<h3>The vapor pressure of the volatile solvent</h3>

The formula for the vapor pressure of the volatile solvent is given as

P = NP°

Using Raoult's law

N is defined to be the mole fraction

Po is the vapor pressure.

From P =  NP°

N = P/P°

N = 18.5/26.5

N = 0.6981

<h3>The  mole fraction</h3>

1-  0.6981

= 0.3019

The mole fraction of the solute is given as  0.3019

Answer:

First definition:

  • Duru's definition: A line segment is a line connecting two endpoints

                                               ⇅

  • Teacher's comment: What you've written is true, but it isn't a correct definition. A ray would also fit your defenition

Second definition:

  • Oliver's definition: A line segment is when three points are all on the same line.

                                                ⇅

  • Teacher's comment: Were you thinking of the team collinear?

Third definition:

  • Carlos' definition: A line segment is<u> part of a line,</u> not the whole thing.

                                               ⇅

  • Teacher's comment: I think you have the right idea, but you need to be more careful with your language.

Explanation:

A line segment is <u>part of a line</u> that connects points. It limited consequently, it has length.

  • Duru's definition: A line segment is a line connecting two endpoints

                                               

It is missing that it is just a part of the line. A ray also connects two points but extends infinetly in one direction. Thus,  Duru's definition is not so specific.

That justifies teacher's comment:

  • Teacher's comment: What you've written is true, but it isn't a correct definition. A ray would also fit your defenition

Second definition:

  • Oliver's definition: A line segment is when three points are all on the same line.

 

The constraint of a line segment to three points all on the same line corresponds to collinear points. Two points always form a line,, but three points lie on a line only in they are collinear.

That justifies, theacher's comment:                          

  • Teacher's comment: Were you thinking of the team collinear?

Third definition:

  • Carlos' definition: A line segment is part of a line, not the whole thing.

Mathematicall language is formal. You must use precise words. An expression as 'whole thing" is not formal.

That justifies teacher's comment:

  • Teacher's comment: I think you have the right idea, but you need to be more careful with your language.

Answer:

The Correct Answer Would Be No force is needed

Explanation:

an object in motion stays in motion.

<u>Newton's first law of motion</u> - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
