The value of molarity is 1.589mol/dm3.

While molarity is concerned with the moles of a solute in respect to the volume of a solution, molality discusses the moles of a solute in relation to the mass of a solvent.

The quantity of a material dissolved in a given mass of solvent is known as its molality (m), also known as molal concentration. The moles of a solute per kilogram of a solvent are how it is defined.

The quantity of a material in a specific volume of solution is known as its molarity (M). The number of moles of a solute per liter of a solution is known as molarity. The molar concentration of a solution is another name for molarity.

Molarity equation : M = moles solute / liters solution

Given data

liters of solution = 230ml

mass = 11.7g

    moles of solutes = mass/molar mass

    molar mass of CH3OH= C(12)+H(1*3) +O(16)+1 =32g

      so,  moles of solutes= 11.7g/32g =0.365mol.

Molarity= 0.365mol/230*10^-3 = 0.365mol/0.230L= 1.589mol/dm3.

0.000107 mol is the concentration of a NaOH solution if 26.96 ml are needed to titrate 0.5930 g of KHP.

KHP, also known as potassium hydrogen phthalate, is an acidic salt chemical. It produces a colorless solution, a white powder, colorless crystals, and an ionic solid that is the monopotassium salt of phthalic acid.

Moles of KHP= 0.5930/204.22g/mol

Moles of KHP=0.0029mol

now when26.96 ml are needed

concentration=0.0029/26.96

Concentration=0.000107 mol

Hence,0.000107 mol is the concentration of a NaOH solution if 26.96 ml are needed to titrate 0.5930 g of KHP.

The percent of chloride ion in a sample if 2. 500 g of the sample produces 1. 750 g of agcl when treated with excess ag⁺ is 17.2 percent.

What is mass percent?

The ratio of the mass of the solute contained in a solution to the mass of the solution as a whole is known as the mass percent.

Explanation:

Given:

Mass of sample = 2. 500 g

Mass of AgCl = 1. 750 g

The percent of chloride ion in a sample is calculated as,

Molar mass of AgCl = 143.32 g/mol

[tex]Molar mass of Chlorine atom = 35.45 g/mol[/tex]

Assume that all of the sample's chlorine has precipitated into silver chloride. As a result, the amount of chlorine in silver chloride will match the amount of chlorine in the sample.

First we have to find mass of chlorine,

[tex]In 143.32 g of silver chloride, mass of chlorine present is 35.45 gSo, in 1.3487 g of silver chloride, mass of chlorine present will be =35.45g/143.32 g * 1.750 g = 0.43 g[/tex]

Therefore, the percent of chloride ion in a sample is

[tex]Mass of pure chloride compound = 2.500 gMass of chlorine = 0.43 g%Chlorine = 0.43/2.5 *100%Chlorine = 17.2 %[/tex]

Hence, the percent of chloride ion in a sample is [tex]17.2%[/tex] percent.

Answer: C

Explanation: because Pangaea broke apart and made smaller continents.

Explanation:

We have to balance the following equation:

__ H₂O + __ F₂ -------> __ HF + __ O₂

First we have to determine the number of atoms of each element that we have on both sides of the equation.

__ H₂O + __ F₂ -------> __ HF + __ O₂

O: 1 O: 2

H: 2 H: 1

F: 2 F: 1

We have 2 atoms of O on the right side and 1 atom of O on the left side. To balance the O atoms we can change the coefficient for H₂O and write a 2 in front of it.

2 H₂O + __ F₂ -------> __ HF + __ O₂

O: 2 O: 2

H: 4 H: 1

F: 2 F: 1

Then we have 4 atoms of H on the left and 1 atom of H on the right side of the equation. We can change the coefficient for HF to balance the H atoms.

2 H₂O + __ F₂ -------> 4 HF + __ O₂

O: 2 O: 2

H: 4 H: 4

F: 2 F: 4

And finally we have 2 atoms of F on the left and 4 atoms of F on the right. We can change the coefficient for F₂ and write a 2 there.

2 H₂O + 2 F₂ -------> 4 HF + __ O₂

O: 2 O: 2

H: 4 H: 4

F: 4 F: 4

The equation is balanced.

Answer: 2 H₂O + 2 F₂ -------> 4 HF + O₂

Iron – Ferrum (Fe)

Iron's Latin name, 'ferrum', gives it its symbol Fe; it simply means 'iron' or 'sword', and is possibly of Semitic origin.

Answer:

274.2 K

Explanation:

to get from Fahrenheit to Celsius you use your known value, 34 F, and subtract it by 32 = 2, then you multiply it by 5/9 (or .5556) = 1.1 C

to get from Celsius to Kelvin, you just add 273.15, therefore your Kelvin would be 274.2.

(no hablas ingles..)

para pasar de Fahrenheit a Celsius usas tu valor conocido, 34 F, y lo restas por 32 = 2, luego lo multiplicas por 5/9 (o .5556) = 1.1 C

para pasar de Celsius a Kelvin, solo sumas 273,15, por lo que tu Kelvin sería 274,2.

Here, we want to know what happens to a solution that becomes more acidic

A lesser ph (1-7) indicates acidity with the acidity being higher as the number becomes smaller

What this means is that a solution with a pH of 3 is more acidic than a solution with a pH of 5

Thus, when the acidity increases, it is expected that the pH of the solution decreases (it becomes smaller in number)

As the molecular weight increases, polymers tend to crystallize due to how harder it is for chains that are side by side to align due to the increasing length of the chain which makes it difficult to turn out the ordered atomic array.

Polymers can be natural or synthetic substances. Polymers can be crystalline or amorphous, depending on how their molecular chains are structured.

Polymers are found in proteins and nucleic acids. Crystalline polymers, have chains that are positioned together, they don't bend easily under pressure. A typical example of a crystalline polymer is a diamond-hard structure.

In summary, whenever there is an increase in molecular weight, there is always a notable decrease in crystallinity. The crystallinity of a polymer generally affects its properties which include properties such as the density of the polymer and its hardness.
