Desired molarity
WebMolarity (moles/liter) is a common expression of concentration. When making a solution of a particular molarity, you need to know three things: the desired molarity, the desired volume and the formula weight of the compound to be dissolved. The best place to find the formula weight (grams/mole) is on the chemical’s bottle. WebOnce the molecular weight of the solute is known, the weight of chemical to dissolve in a solution for a molar solution less than 1M is calculated by the formula: grams of chemical = (molarity of solution in mole/liter) x (MW of chemical in g/mole) x …
