This is a list of prices of chemical elements. Listed here are mainly average market prices for bulk trade of commodities. Data on elements' abundance in Earth's crust is added for comparison. As of 2020, the most expensive non-synthetic element by both mass and volume is rhodium.
Sodium chloride / ˌ s oʊ d i ə m ˈ k l ɔːr aɪ d /, [8] commonly known as edible salt, is an ionic compound with the chemical formula NaCl, representing a 1:1 ratio of sodium and chlorine ions. It is transparent or translucent, brittle, hygroscopic , and occurs as the mineral halite .
Note: ρ is density, n is refractive index at 589 nm, [clarification needed] and η is viscosity, all at 20 °C; T eq is the equilibrium temperature between two phases: ice/liquid solution for T eq < 0–0.1 °C and NaCl/liquid solution for T eq above 0.1 °C.
To create the solution, 11.6 g NaCl is placed in a volumetric flask, dissolved in some water, then followed by the addition of more water until the total volume reaches 100 mL. The density of water is approximately 1000 g/L and its molar mass is 18.02 g/mol (or 1/18.02 = 0.055 mol/g).
Morocco is a fairly stable economy with continuous growth over the past half-century. Current GDP per capita grew 47% in the 1960s, reaching a peak growth of 274% in the 1970s. However, this proved unsustainable and growth scaled back sharply to just 8.2% in the 1980s and 8.9% in the 1990s. [28]
The mining industry of Morocco is important to the national economy. Morocco is the world's largest producer of phosphate , and contains about 75% of the world's estimated reserves. [ 1 ] Mining contributed up to 35% of exports and 5% of GDP in 2011. [ 2 ]
Price of silver. Silver cost $4 per troy ounce in 1992, [67] started to rise rapidly in early 2004, [67] reached $18 per troy oz by late 2007, slipped badly to $10 per troy oz during the Credit Crunch of 2008, [67] but was selling in late 2009 and again in early 2010 at just under $18 per troy oz of metal.
