The number in a mole is called Avogadro's number: 6.022142 x 10 23, after the 19th-century Italian scientist who first proposed how to measure the number of molecules in a gas. Using our unit conversion techniques, we can use the mole label to convert back and forth between the number of particles and moles. As you learned, the mass number is the sum of the numbers of protons and neutrons present in the nucleus of an atom. molar mass and molecular weight.
