Semmy [17]

Answer:

Explanation:

It is not correct to say that an object with the largest volume has the largest mass.

Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.

Mass is the amount of matter in a substance. Volume is the space a body occupies.

A balloon and a stone for example is a typical one.
A balloon has more volume but far lesser mass compared to a stone.
A stone, gravel sized has low volume but more massive than a balloon.

Therefore, it is wrong to say a balloon has more mass because it has more volume.

Suppose you have been given the task of distilling a mixture of hexane + toluene. Pure hexane has a refractive index of 1.375 an

miv72 [106K]

Explanation:

The given data is as follows.

Refractive index of mixture = 1.456

Refractive index of hexane = 1.375

Refractive index of toulene = 1.497

Let mole fraction of hexane = $x_{1}$

and, mole fraction of toulene = $x_{2}$

Also, $x_{1} + x_{2} = 1$

or, $x_{1} = 1 - x_{2}$

Hence, calculate the mole fraction of hexane as follows.

refractive index mixture= mole fraction hexane × ref index hexane + mole fraction toluene × ref index toluene.

1.456 = $(1 - x_{2}) \times 1.375 + x_{2} \times 1.497$

1.456 = $1.375 - 1.375x_{2} + 1.497x_{2}$

0.081 = $0.122x_{2}$

$x_{2}$ = $\frac{0.081}{0.122}$

= 0.66

Since, $x_{1} = 1 - x_{2}$

= 1 - 0.66

= 0.34

Thus, we can conclude that mole fraction of hexane in your sample is 0.34.
