We can solve this by the method of which i solved your one question earlier
so again here molar mass of C12H25NaSO4 is 288.372 and number of moles for 11900 gm of C12H25NaSO4 will be = 11900/288.372
which is almost = 41.26 moles
so to get one mole of C12H25NaSO4 we need one mole of C12H26O
so for 41.26 moles of C12H25NaSO4 it will require 41 26 moles of C12H26O
so the mass of C12H26O = 41.26× its molar mass
C12H26O = 41.26×186.34
= 7688.38 gm!!
so the conclusion is If you need 11900 g of C12H25NaSO4 (Sodium Lauryl Sulfate) you need C12H26O 7688.38 gm !!
Again i d k wether it's right or wrong but i tried my best hope it helped you!!

Pedro adds 3.23 moles of helium to a balloon that already contained 4.51 moles of helium creating a balloon with a volume of 9.87 liters. What was the volume of the balloon before the addition of the extra gas?
Answer:
7.The answer is 2.13 because if u add 3.23 and 4.51 and the answer is 7.74 and u add 2.13 to get 9.87. 3.23 + 4.51 + 2.13 is 9.87

How does the kinetic theory of gases explain the weather changes happening in the troposphere? You can also research on the internet using keywords such as troposphere, atmosphere layers, and weather changes.
Answer: According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often.

How many joules are required to heat 15 grams of ice from -200⁰ to 1400⁰ C?
Answer: A heat energy of 50160 joules are required to heat 15 grams of ice from [tex]-200^{o}C[/tex] to [tex]1400^{o}C[/tex].
Explanation:
Given : mass of ice = 15 g
Convert grams into kg as follows,
[tex]1 g = 0.001 kg\\15 g = 15 g \times \frac{0.001 kg}{1 g}\\= 0.015 kg[/tex]
Initial temperature = [tex]-200^{o}C[/tex]
Final temperature = [tex]1400^{o}C[/tex]
Formula used to calculate the amount of heat energy is as follows.
[tex]q = m \times C \times (T_{2} - T_{1})[/tex]
where,
q = heat energy
m = mass of substance
C = specific heat of substance (ice here has C = [tex]2090 J/kg ^{o}C[/tex])
[tex]T_{1}[/tex] = initial temperature
[tex]T_{2}[/tex] = final temperature
Substitute the values into above formula as follows.
[tex]q = m \times C \times (T_{2} - T_{1})\\= 0.015 kg \times 2090 J/kg^{o}C \times [1400 - (-200)]^{o}C\\= 50160 J[/tex]
Thus, we can conclude that 50160 joules are required to heat 15 grams of ice from [tex]-200^{o}C[/tex] to [tex]1400^{o}C[/tex].

Shoals are raised landforms made of sand and gravel that are commonly found in Florida. They are often called sandbars and are located in and around bodies of water such as oceans, rivers, and lakes. Which factor most commonly causes shoals to form or change shape?
Heavy rain fall most commonly causes shoals to form or change shape making depressions and bars in the sand.
What causes a shoal ?Wave shoaling occurs when surface waves slow down, their wave height rises, and the space between waves narrows as they approach shallow water, like a beach. The waves are said to shoal because of this action, which is known as shoaling.
The shoal, a buildup of silt that might be hazardous to ships in a river channel or on a continental shelf.
Conventionally, it is assumed that the continental shelf is less than 10 metres below sea level at low tide. Shoals are created mostly by the same processes that result in offshore bars.
Thus, Heavy rain fall causes shoals to produce and change shape creating depressions and bars in the sand.

why should a sports person or a rickshaw puller in take more corbohydrate rich food in their diet
Answer:
Because carbohydrates are energy
Explanation:
Carbohydrates is best best nutrient for energy, turning into energy as soon as they are eaten. A rickshaw puller most likely needs quite a bit of energy to pedal all day without getting tired, so that's why they eat a carbohydrate rich diet.
A gas occupies 2.50 L at 1.5 atm. What will be the volume of this gas if the

catalyst
→ water +X
Given the equation:
To which class of organic compounds does product X belong?
1. alcohol
2. Ester
3. Ether
4. 4. alkane
Answer: X is an Esther
Explanation: alcohol and carboxylate acid forms esters
When a carboxylic acid and alcohol react then-new substance is produced from esterification and hence is called an ester. Thus, option 2 is correct.
What is esterification?Esterification is the process to make esters from carboxylic acids and alcohol in the presence of an acid catalyst (dry sulphuric acid). The -COOH group of the carboxylic acids contributes to the formation of the esters.
The esterification reactions are reversible reactions and occur at a slower pace. The reaction between an acid and alcohol is shown as:
Butanoic acid + 1-pentanol (catalyst) → water + ester
Therefore, option 2. ester is produced.

A scuba diver is using scuba gear to breathe under water. The pressure on her lungs is 2.5 atm and her lung volume is 4.4 L. What will happen to the volume of her lungs when the pressure increases to 4.5 atm?
Answer:
2.44 LExplanation:
The volume can be used by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2 \\ [/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the final volume
[tex]V_2 = \frac{P_1V_1}{P_2} \\[/tex]
We have

What is the concentration of each ion in a 0.525 mol/L solution of magnesium chloride?
mg=? cl=?
Answer:
Mg⁺² = 0.525 mol/L
Cl⁻ = 1.05 mol/L
Explanation:
The formula for magnesium chloride is MgCl₂, and in a solution the following process takes place:
MgCl₂ → Mg⁺² + 2Cl⁻By analyzing the stoichiometric coefficients, we can tell that the concentration of Mg⁺² ions is the same as the concentration of MgCl₂, while the Cl⁻ concentration is twice that value.
In other words:
Mg⁺² concentration = MgCl₂ concentration = 0.525 mol/LCl⁻concentration = 2 * MgCl₂ concentration = 1.05 mol/Lhelp please!!! no links
