So what is the molar mass of KAlso4 2? Expert reply. The specified compound KA1 (SO4) 2 is potassium aluminum sulfate. It consists of one potassium atom, one aluminum atom, two sulfur atoms and eight oxygen atoms. The molar mass of potassium, aluminum, sulfur and oxygen is 39.10 g / mol, 26.98 g / mol, 32. ### 06Do you also know what 12h2o is? Alum, or potassium aluminum sulfate, is a chemical compound with the formula KA1 (SO4). 12H2O. 12H2O) is mixed with Chromalum (KCr (SO4). 12H2O), so the crystals take on a purple color. ### And what is the molar mass of alum? 474. ### 39 g / molHow is the molar mass determined? The important points
1. Molecular mass is the mass of a specific chemical element or compound (g) divided by the amount of substance (mole).
2. The molar mass of a compound can be calculated by adding the standard atomic masses (in g / mol) of its constituent atoms.

### Mass of one mole of water = 2 g / mole + 16 g / mole = 18 g / mole What is the difference between alum and aluminum?

The main differences between alum and aluminum hydrochloride

### How do you find the theoretical yield of alum?

You can use the molar mass of alum to determine the grams of moles. Finally, for the yield%, there is the effective yield (12.77 g) divided by the theoretical yield (x 100%).

### How do you like the audience?

Divide the object’s weight by the acceleration of gravity to find its mass. You have to convert the weight units to Newtons. For example, 1 kg = 9.807 N. If you measure the mass of an object on Earth, divide its weight in Newtons by the acceleration of gravity (9.8 meters / second2) to get the mass.

### How many moles are there in al2 so4 3?

0.0029226872416366 mol

### 14 neutrons What does so4 3 mean?

In the chemical formula Al2 (SO4) 3, Al2 means that there are two aluminum (atoms or ions). SO4 is a sulfate ion and (SO4) 3 means there are 3 sulfate ions. The number 3 for Al2 (SO4) 3 means that the chemical formula contains three times as many atoms and ions.

### How is the dividend percentage calculated?

To express the efficiency of a reaction, the percentage yield can be calculated using this formula: yield = (actual yield / theoretical yield) x 100. A percentage yield of 90 means that the reaction is 90% efficient and efficient at 10% it was. some materials were wasted (they did not respond or their products were not tracked).

### What is atomic mass in science?

The mass or atomic weight is the average mass of protons, neutrons and electrons in an atomic element.

### What is the mass of sodium?

The atomic mass of sodium is said to be 23.

### KAl (SO4) 2 POTASSIUM ALUMINUM SULFATE What is alum chemistry?

Alum, one of a group of double hydrogenated salts usually consisting of aluminum sulfate, water of hydration and sulfate of another element. Aluminum potassium sulfate, also known as aluminum potassium or aluminum potassium, has the empirical formula K2 (SO4) Al2 (SO4) 3 24H2O or KA1 (SO4) 2 12H2O.

### What is the difference between molecular weight and molecular weight?

Molecular weight is the mass of one molecule of a compound, while molecular weight is the mass of one mole of a compound.

### What has a mass of 1 amu?

An atomic mass unit (symbolizing AMU or Amu) is defined exactly as 1/12 of the mass of a carbon12 atom. The carbon-12 (C12) atom has six protons and six neutrons in its nucleus. Under inaccurate conditions, an AMU is the average of the resting mass of the proton and the resting mass of the neutron.

### 997 g / mol What is the molecular weight in chemistry?

In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of the compound divided by the amount of the substance in the sample, measured in moles. In the International System of Units (SI), the basic unit of mass molar is kg / mol.

36.46 g / mole
