Select all possible structures with a molecular ion at 55, an absorption in its ir spectrum at ~2250 cm-1 and no absorption in its ir spectrum above 3000 cm-1. assume each compound has an sp3 hybridized c-h absorption in its ir spectrum.

answer; i do believe the correct answer is (river); /// good luck

the density of gold = 19.3 g/cm3

the relation between density and mass and volume is

density = mass / volume

given :

mass of gold = 13 g

density = 13g / volume = 19.3

volume = 13 /19.3 = 0.67 cm^3

thus volume of gold nugget = 0.67 cm^3
