For chemistry you often need to convert moles to grams and grams to moles. Chemistry. E.g. The Avogadro's number is a dimensionless quantity and is equivalent to the Avogadro constant, which is 6.02 x 10^23 for one mole of a substance. The mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass. If the container holding the gas is rigid rather than flexible, pressure can be substituted for volume in Avogadro's Law. To calculate the number of molecules, we must first know the total number of moles in 30 grams of sodium sulfate. For moles, the unit is simply moles. To convert from molecules to grams, it is necessary to first convert the number of molecules of a substance by dividing by Avogadro's number to find the number of moles, and then multiply the number of moles by the molar mass of this substance. Then, knowing that there are 6.022x10^23 molecules in one mol (Avogadro's number) you can find the number of molecules in however many mol of the substance that you have. Moles are also convenient ways of measuring the mass of an object. - [Instructor] In a previous video, we introduced ourselves to the idea of average atomic mass, We know we have 10 g of HCl, and it has a molecular weight of 36.5 g / mol.
