Question

In 1961, scientists agreed that the atomic mass unit (amu) would be defined as 1/ 12 the mass of an atom of 12C. Before then, it was defined as 1 /16 the average mass of an atom of naturally occurring oxygen (a mixture of ¹⁶O, ¹⁷O, and ¹⁸O). The current atomic mass of oxygen is 15.9994 amu. (a) Did Avogadro’s number change after the definition of an amu changed and, if so, in what direction? (b) Did the definition of the mole change? (c) Did the mass of a mole of a substance change? (d) Before 1961, was Avogadro’s number 6.02x10²³ (to three significant figures), as it is today?
