Legend says that archimedes, in determining whether or not the king's crown was made of pure gold, measured its volume by the wa
ter displacement method. if the density of gold is 19.3 g/cm3, and the crown's mass is 600 g, what volume would be necessary to prove that it is pure gold?
Mass=volume x density if we have mass and density we can calculate volume using the formula: volume=mass/density volume of the displaced water = 600g/19.3g/cm3 volume = 31.09cm3
Empirical formula is when the molecular formula is reduced (each element) by the same number until you are unable to do so any further. CH2O cannot be further reduced, but C3H6O3 can all be divided by 3 making it CH2O (same empirical formula)
