The numerical value of Avogadro's number, usually written as No, is a consequence of the arbitrary value of one kilogram, a block of Pt-Ir metal called the International Prototype Kilogram, and the choice of reference for the atomic mass unit scale, one atom of carbon-12. To avoid toomuch space, write your answer in scientific notation. Determine the number of CH2Cl2 molecules in 25.1 g CH2Cl2. How Did James Hunt Die, The procedure for calculating molecular masses is illustrated in Example 1. i: 1, On the molar level, they are interpreted in terms of moles.
