### Relative density Wikipedia

Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, air at room temperature (20 °C or 68 °F) is the reference. The term "relative density" is often preferred in

### How to Find and Determine the Specific Gravity of a Rock

What specific gravity is, is the mass of a solid in relationship to its weight. An extreme example of this is the difference in volume of a pound of feathers and a pound of gold. You could very easily put a pound of gold into your pocket and walk away with it but try and put a pound of feathers into your pocket. Your pocket just isn’t big enough. If you take a block of sandstone that is 2

### Calculate :: Specific Gravity :: Coins :: Gold :: Silver

'The Specific Gravity of the Gold Coins of Aksum' by W. A. Oddy and S. C. Monro-Hay in 'Metallurgy in Numismatics' by Metcalf and Oddy, 1980. This stone showed gold of 94% = SG of 18.5, 92% = SG 18.15, 91% = SG of 18.01. Also 'The stone composition of Parthian Coins' by E. R. Caley, chapter VII in 'Numismatic Notes and Monographs' #129, ANS, 1955, which has a Table XXIV, of silver content

### 3 Ways to Test the Specific Gravity of Liquids wikiHow

08/04/2019· Specific gravity, also referred to as relative density, is used to relate the weight or density of liquids to that of water. Specific gravity is a unitless measurement that is derived as a ratio of either the weight of another liquid or the density of another liquid divided by the weight or density of water.

### Specific Gravity Recreational Gold Prospecting

31.1 = This is the number of grams per ounce of gold; Original dry weight = 96 grams / 31.1 = 3.08 ounces. Subtract the gold weight from the dry weight. 3.08 ounces 1.56 ounces = 1.52 ounces. Therefore what is left is 1.52 ounces of quartz. The specific gravity for gold is 19.3. The specific gravity for quartz is 2.65.

### Density of Gold, Silver, Platinum Chards

For most practical purposes, density and specific gravity are the same, however there are slight differences between them, as most scientists would appreciate. Density . Density is defined as the ratio of the mass of an object to its volume. Density should correctly be expressed in units of "unit mass per unit volume", e.g. grams per cubic centimetre. The figure quoted is often the same as
