The specific heat of an unknown metal is found to be 0.233 J/K g. The Law of Dulong and Petit predicts a molar heat capacity of 26 J/K mol. Use this law to estimate the molar mass of the metal.
Consider equimolar samples of different ideal gases at the same volume and temperature. Gas A has a higher molar mass than gas B.
Why can the nature of the metal salt precursor be changed during the epoxide addition method so easily without altering
