What is the molecular weight (mass) for KOH?
The molecular mass of a chemical compound is defined as the mass of a sample (in moles) of that compound divided by the quantity of chemical substance in that sample. The molar mass is a mass property of a substance, not a molecular property. The molecular mass or weight is usually expressed in grams.
The relative atomic masses of each element present in a molecule can be added to determine the molecular mass of that compound. Also, the chemical formula can be used to determine the number of atoms in a molecule.
Potassium hydroxide (KOH) is the composition of potassium, oxygen, and hydrogen. KOH is a base is made up of alkali metal hydroxide, which is a very potent alkali metal. When it is in its aqueous state has the appearance of a transparent solution. In its solid state, this chemical does not have a distinctive odor.
The steps to be followed to find KOH molecular mass are:
Potassium hydroxide molecular formula is KOH according to which we can find the number of atoms in a molecule.
Next, using the mass of potassium, oxygen, and hydrogen, given in the Periodic Table, calculate the atomic mass of each element.
Then, multiply the subscript representing the number of atoms by the atomic mass of that element.
At last add the atomic masses in the molecule to get the molecular mass.
Thus, when the atomic masses of potassium, oxygen, and hydrogen, are rounded to four significant figures, the molecular mass will be:
KOH= Atomic mass of K + Atomic mass of O + ( Atomic mass of H)
KOH = (39.09) + (16.00) + (1.008)
KOH = 56.1g .
Potassium hydroxide is used in food as a pH adjuster, stabilizer, and thickener. Based on the observance of various good manufacturing practice conditions of use, the FDA has determined that this ingredient is generally safe as a direct human food ingredient.
