If 190dm of hydrogen gas collected at 20°c and 760mmHg .Calculate it's volume at stp (standard pressure=760mmHg

Answers

Answer:

177.1 L

Explanation:

The excersise can be solved, by the Ideal Gases Law.

P . V = n . R . T

In first step we need to determine the moles of gas:

We convert T° from, C° to K → 20°C + 273 = 293K

We convert P from mmHg to atm → 760 mmHg = 1atm

1Dm³ = 1L → 190L

We replace: 190 L . 1 atm = n . 0.082 . 293K

(190L.atm) / 0.082 . 293K = 7.91 moles.

We replace equation at STP conditions (1 atm and 273K)

V = (n . R .T) / P

V = (7.91 mol . 0.082 . 273K) / 1atm = 177.1 L

We can also make a rule of three:

At STP conditions 1 mol of gas occupies 22.4L

Then, 7.91 moles will be contained at (7.91 . 22.4) /1 = 177.1L

What is measurment?

Measurment is a process by which we can measure any physical quantity with the help of different apparatus. For example if one can want to measure the distance than he can use the a simple measuring scale.

Distance can be measured in kilometer,meter, centimeter etc. Temperature can be measured with the help of glass tube thermometer as glass tube is a simple temperature measuring appratus and glass tube thermometer is used to measure temperature in fahrenheit (F).

Measurment is a general process which can be used by a common person in his daily life. Every common thing which we use in our routine life need to be measured like if we buy sugar it will be measured in kilogram or gram. If a person buy milk it can measured in liter.

Para solucionar el ejercicio primero se debe conocer el número atómico de los elementos para determinar cuantos electrones tiene cada uno N: número atómico 7, tiene 7 electrones Nivel 1: 2 electrones Nivel 2: 5 electrones P: número atómico 15, tiene 15 electrones Nivel 1: 2 electrones Nivel 2: 8 electrones Nivel 3: 5 electrones Cl: número atómico 17, tiene 17 electrones

Answers

Answer:

El número atómico se refiere al número de protones o electrones de un átomo.

Explicación:

El número atómico se refiere a la cantidad de protones o la cantidad de electrones que giran alrededor de las capas u órbita de un átomo, por lo que el número atómico 7 representa que el átomo tiene 7 electrones o protones mientras que, por otro lado, el número atómico 17 muestra el número de electrones o protón. Solo hay dos electrones que entran en la primera órbita y en el resto de las capas tiene espacio para 8 electrones por lo que los átomos pierden o agregan electrones en su capa más externa para obtener estabilidad.

Explanation:

The ability of a material, the solute, to combine with some other substance, the solvent, is known as solubility. Temperature of the water to the nearest degree is 110 °C for the given solubility.

The ability of a material, the solute, to combine with some other substance, the solvent, is known as solubility in chemistry. Insolubility, or the solute's inability to create such a solution, is the opposite property.

The concentration of a solute inside a saturated solution—a solution where no more solute could be dissolved—is typically used to gauge the degree of a substance's solubility in a particular solvent. Temperature of the water to the nearest degree is 110 °C for the given solubility.

21.82 L of 4.65 M HCl is added to 9.31 L of 8.55 M NaOH. What is the concentration of HCl in the resulting solution? **hint: make ICE table

A)1.90 M

B)0.952 M

C)10.3 M

D)0.702 M

E)0.644 M

Answers

Answer:

D

Explanation:

First you multiply 4.65 with 21.82 to get the mols of hcl, which is 101.463. Then you make an ice table. The ice table should look like this:

HCl       +  NaOH     =  12NaCl + H2O

101.463   6.022e23   1.989e30

As the ice table above shows, you will have 1.989e30 mols of nacl after the reaction. With that information, you can then divide it by 2.833333333333333e30 to get 0.702 M.

10 moles of potassium hydroxide in 5.16 L of solution

Answers

Answer:

The molarity is 8.52M

Explanation:

molality = moles of solute/kg of solvent = 5.2mol/kg

moles of solute = 5.2mole

mass of solute = moles of solute × MW = 5.2 × 56.106 = 291.8g

mass of solvent = 1kg = 1000g

Mass of solution = mass of solute + mass of solvent = 291.8g + 1000g = 1291.8g

Density of KOH = 2120g/L

Volume of solution = mass/density = 1291.8/2120 = 0.61L

Molarity = number of moles of solute/volume of solution = 5.2/0.61 = 8.52M

The concentration in the solution is 1.94 mol/L

From the question,

We are to determine the concentration of 10 moles of potassium hydroxide in 5.16 L of solution.

From the formula

Number of moles = Concentration × Volume

Then, we can write that

[tex]Concentration = \frac{Number\ of\ moles}{Volume}[/tex]

From the question,

Number of moles of potassium hydroxide (KOH) = 10 moles

Volume of solution = 5.16 L

∴ Concentration of the solution = [tex]\frac{10}{5.16}[/tex]

Concentration of the solution = 1.94 mol/L

Hence, the concentration in the solution is 1.94 mol/L
