you can calculate the overall volume of the solution. Concentration – how much of a mixture is the constituentĪs well as that, if you know the mass.The molar mass – you can calculate it by adding up the molar masses of the elements that make up the compound.In order to do that, however, you need to know a few things:
Molarity chemistry calculator how to#
How to use the molarity calculatorĮssentially, you’re going to use this calculator to convert grams per milliliter to moles. To dilute a solution of concentrated acid or base of known w/w strength, please use the Acid & Base Molarity Calculator. To dilute a solution of known molarity, please use the Solution Dilution Calculator. Avogadro’s number, NA, has a value of 6.022140857×10 23 mol −1. The molarity calculator calculates the mass of compound required to achieve a specific molar concentration and volume. Avogadro’s constantĪvogadro’s constant, named after Amedeo Avogadro, is a physical constant that is the number of atoms in 12 grams of carbon-12, the most common isotope of carbon. This definition is equivalent to Avogadro’s number, which has been used since about 1811 for this purpose. It was adopted by an international agreement in 1971 and defined as “the number of entities equal to one mole” (symbol mol).
The mole is the amount of a substance that contains as many elementary entities as there are atoms in 12 grams of carbon-12 ( 12C). The name comes from the Greek word μολος, which means a small portion or morsel. Meant to be used in both the teaching and research laboratory, this calculator (see below) can be utilized to perform a number of different calculations for preparing molar solutions when starting with the solid material.
The mole is the SI base unit of the amount of substance. Free Online Chemistry Calculators, including periodic table, molecular weight calculator, molarity, chemical equation balancer, pH, boyles law, idea gas law etc.
