How is Ca OH 2 formed?
Calcium hydroxide is formed by the action of water on calcium oxide, also called slaked lime, Ca(OH)2. A small proportion of it dissolves when combined with water, forming a solution known as limewater, the remainder remaining in a suspension called lime milk.
How do you calculate formula masses?
To calculate formula mass, multiply the subscript of each element in the formula by the element's atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.

What is the equivalent mass of Ca OH 2?
The molecular weight of an element, molecule or ion divided by its valence (or valence change for a redox reaction). For example, the molecular weight of calcium hydroxide, or "slaked lime," (Ca(OH)2) is 72.10. Because the valency of calcium in this case is 2, the equivalent weight of lime is 36.05.
What is meant by formula mass?
The formula mass of a substance is defined as the sum of the atomic masses of constituent atoms in an ionic compound. This is generally used for ionic compounds which do not contain discrete molecules, but ions as their constituent units.
What is unit formula mass?
The mass of the formula unit of a substance is the sum of the atomic masses of all atoms in an ionic compound's formula unit. A formula unit in chemistry is the analytical formula used as a separate body for stoichiometric measurements of any ionic or covalent network solid compound.

What is equivalent mass formula?
The formula to calculate the equivalent mass of an element is given by. Equivalent Mass = Atomic Mass Valency .
How do you find the equivalent mass?
To calculate the equivalent mass of a base, simply divide the molar mass of the base by the number of hydroxyl groups. Take, for example, calcium hydroxide Ca(OH)₂. A few simple calculations yield an equivalent of 37g/mol. To find the equivalent of an acid, divide the acid's molar mass by the number of protons.
How do I calculate formula mass?
To calculate formula mass, multiply the subscript of each element in the formula by the element's atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.
How is formula unit mass calculated?
To calculate the formula unit mass, find out the number of atoms of every element present in the chemical formula. Add together the relative atomic mass values for all the atoms of every element present.
