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

What’s (2a) with an exponent of 6/5 in radical form?
VashaNatasha [74]
<h3>Answer: Choice A</h3>

Reason:

Use the rule that a^{b/c} = \sqrt[c]{a^b} = \left(\sqrt[c]{a}\right)^b

This means, (2a)^{6/5} = \sqrt[5]{(2a)^6} = \boldsymbol{\left(\sqrt[5]{2a} \ \right)^6}

As another example, m^{2/3} = \sqrt[3]{m^2} = \left(\sqrt[3]{m} \ \right)^2

Choose the excerpt that is from an opera aria by Mozart:
Irina-Kira [14]

The excerpt that is from an opera aria by Mozart is; Excerpt A

What is the given Excerpt?

Mozart was an Austrian composer, widely recognized as one of the greatest composers in the history of Western music. Unlike any other composer in musical history, he wrote in all the musical genres of his day and excelled in every one. His taste, his command of form, and his range of expression have made him seem the most universal of all composers; yet, it may also be said that his music was written to accommodate the specific tastes of particular audiences.

Mozart wrote several successful operas, such as The Marriage of Figaro (1786), Don Giovanni (1787), and The Magic Flute (1791). Mozart also composed a number of symphonies and sonatas. His last symphony—the Jupiter Symphony—is perhaps his most famous.

The given excerpt which is seen from an audio listened to online is seen to be Excerpt A.

The diagram below depicts the international flow of funds in the 1920s.
Arada [10]

Number 1 represents the reparation payments from Germany to France and Britain.

<h3>What is the flow of funds?</h3>

The flow of funds implies the movement of money from one person or entity to another. In the case of the international flow of funds, this occurs as money moves from one country to another.

<h3>What does number 1 represent?</h3>

Considering number 1 occurs from Germany to France and Britain, it likely represents reparation payments. This is because by the end of the First World War in 1918 Germany had to pay a lot of money to the countries affected by its war actions, which included France and Britain.

Therefore, money flowed from Germany to France and Britain as shown in the diagram.

Note: This question is incomplete because the diagram and question are not provided. Here I attach the diagram and question.
