How to Convert From Moles Per Liter to Percentage

Apr 26, 2018Multiply the density of the solution by 1,000 ml (1 liter) to calculate the mass of the 1L of the solution. For example, if the density of 0.5 M KCl solution is 1.1 g/ml, the weight of 1 liter of the solution is 1.1 x 1,000 = 1,100 g.

How to calculate the equivalent weights

Aug 02, 2017Equivalent weight of a substance is referred to as mass per unit valance reacting, of that particular substance, in a redox reaction. The simplest method to calculate the equivalent weight is to divide molar mass of the substance by its valency. Moreover, equivalent weight describes the % share of each atom in any molecule.

Mass versus weight

In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of matter in an object, whereas weight is the force exerted on an object by gravity. In other words, an object with a mass of 1.0 kilogram weighs approximately 9.81 newtons on the surface of the Earth, which is its mass multiplied
