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.
Retail prices vary widely between countries, brands, bottle sizes (0.33 liter to 20 liters) and place of sale (supermarket, fair, restaurant etc.). They range from US$0.05 to US$6 per liter, equivalent to US$50 to US$6,000 per cubic meter .
The decomposition is accelerated by carbon dioxide at Earth's atmospheric levels - around 4 parts per ten thousand. [6] [15] It is a white solid with the orthorhombic crystal structure. [16] Sodium hypochlorite can also be obtained as a crystalline pentahydrate NaOCl·5H 2 O, which is not explosive and is much more stable than the anhydrous ...

For watering plants to use sodium chloride (NaCl) as a fertilizer, moderate concentration is used to avoid potential toxicity: 1–3 grams (0.035–0.106 oz) per liter is generally safe and effective for most plants. [19] [20] [21]
The particular substance sampled may be specified using a subscript, e.g., the amount of sodium chloride (NaCl) would be denoted as n NaCl. The unit of amount of substance in the International System of Units is the mole (symbol: mol), a base unit. [1] Since 2019, the value of the Avogadro constant N A is defined to be exactly 6.022 140 76 × ...
11.6 g of NaCl is dissolved in 100 g of water. The final mass concentration ρ(NaCl) is ρ(NaCl) = 11.6 g / 11.6 g + 100 g = 0.104 g/g = 10.4 %. The volume of such a solution is 104.3mL (volume is directly observable); its density is calculated to be 1.07 (111.6g/104.3mL) The molar concentration of NaCl in the solution is therefore
The restaurant opened on October 8, 1990, in Shenzhen's special economic zone. The South China Morning Post reported that on its opening day, the unique McDonald's received over 40,000 customers ...
