## What is equivalent measurement unit?

You can use equivalent units of mass to convert different units to the same unit for comparison. Equivalent means equal. 1 kilogram is equal to 1,000 grams. 1 milligram is equal to one-thousandths of a gram.

Why equivalent weight has no unit?

An equivalent of a substance is defined as the amount of it which combines with one mole of hydrogen atom or replaces the same number of hydrogen atoms in a chemical reaction. Equivalent weight is a very small number which is basically the ratio of weight by valency, so it is a unit less quantity.

### What is equivalent weight example?

The equivalent weight of an element is the mass which combines with or displaces 1.008 gram of hydrogen or 8.0 grams of oxygen or 35.5 grams of chlorine. These values correspond to the atomic weight divided by the usual valence; for oxygen as example that is 16.0 g / 2 = 8.0 g.

What is the basic unit of weight?

The SI unit of mass is the kilogram (kg). In science and technology, the weight of a body in a particular reference frame is defined as the force that gives the body an acceleration equal to the local acceleration of free fall in that reference frame.

#### What is the SI unit of equivalent conductance?

Answer: ohm⁻¹ cm² g equivalent–¹ The conductance of a solution is a measure of the ability of that solution to carry a current.

Why is equivalent weight calculated?

Equivalent weight is used in the calculation of normality. The normality of a solution is defined as the number of gram equivalents of the solute present per litre of the solution.

## What is number of equivalent?

Equivalent numbers are numbers that have the same value. Each type of number, such as fractions, decimals, or square roots, can be equivalent to other numbers of their types, or to numbers of different types, as long as they have the same value.

What is n factor in equivalent weight?

n factor is atomic weight or molecular weight by equivalent weight. n factor for acids is its basicity,ie, no of replaceable hydrogen ion per molecule.

### What is meant by 1 gram equivalent?

Gram equivalent mass is mass of one mole of element, molecule, ion divided by their valency or number of electrons shared. It’s generally defined for either salts or metals or ions or basically compounds/atoms/molecules which can form ions. For example, molar mass of AlCl3 is 133.34 g/mol.

What are the units of equivalent and molar conductivity?

The molar conductivity unit is Sm2mol-1. The total charge on either anions or cations present in one formula unit of the electrolyte is usually the equivalent factor.

#### What is the unit of equivalent conductance and molar conductance?

∴ Units of Aeq are ohm−1cm2(g−eq−1)

What is normality and equivalent weight?

Normality is the number of equivalent weights, EW, per unit volume. An equivalent weight is the ratio of a chemical species’ formula weight, FW, to the number of its equivalents, n. EW=FWn. The following simple relationship exists between normality, N, and molarity, M. N=n×M.

## How do you calculate the equivalent weight?

1) Gather information about the equivalent weight of the reacting substance. Consult chemical reference books to find out the valence and the molecular weight of the substance. 2) Figure the equivalent weight of the substance. The equivalent weight of the substance is equal to the molecular weight divided by the valence. 3) Calculate normality. Normality is the concentration of the substance of interest in a dissolving liquid. 4) Try an example. Dissolve sodium chloride (NaCl) in water. Sodium chloride has a valence of 1 and a molecular weight of 58.443.

How to calculate the equivalent weights?

To get a more personal assessment of calorie burn, Hirai recommends using a measurement called metabolic equivalent, or METs 0.0175 x MET x weight (in kg) To calculate your weight in kilograms, divide your weight in pounds by 2.2. So, a person

### How to calculate equivalent weight?

Equivalent Weight of Acid and base. In the above formula X represents the valency factor.

• For Acids: The equivalent weight of the acid can be determined by determining the individual molecular weight of each of the elements from the periodic table and firstly adding them
• For Bases.
• Equivalent Weight of the Metal in Salt or Compounds.
• What is the formula of equivalent weight?

What is equivalent weight formula? Equivalent weight (EW) is the molar mass of a substance divided by the n number of equivalents in thesubstance. For acids or bases, the n number of equivalents is thenumber of hydroxide ions in the base (OH-1) , and the number ofhydrogen ions in the acid (H+1).
