liters (L) = moles (mol) / molarity (M) For example, if you need 8 moles of a substance to carry out a reaction and in your laboratory, you have a 2M solution of that substance, you will need 4 L of the 2M solution to carry out the reaction.Recommended...

instead of units of mass or volume as a more appropriate way to express reactants or products in chemical reactions. Mole is a conversion number that allows chemists to move from the microscopic world of atoms, molecules, and ions to the macroscopic world of grams, kilograms, and liters....
Moles to Atoms Formula atoms = mol × 6.02214076 × 1023 Thus, the number of atoms in a substance is equal to the quantity in moles times Avogadro’s constant. Did you know that you can convertliters to molesorgrams to molesusing a similar formula? These conversions are widely used in ...
Based on your understanding of Avogadro's law. 1000 L steel storage tank contains 88.5 kg of methane gas, CH4. Calculate no. of moles. The Attempt at a Solution one method= no. of moles=mass/molar mass. no. of moles= 88500/16.04= 5517.4 moles.other method= 1 mol= 22.4 liter... ...
To calculate the number of moles in a solution given the molarity, wemultiply the molarity by total volume of the solution in liters. How many moles of potassium chloride (KCl) are in 4.0 L of a 0.65 M solution? There are 2.6 moles of KCl in a 0.65 M solution that occupies 4.0 L....
