The Saudi riyal (Arabic: ريال سعودي riyāl suʿūdiyy) is the currency of Saudi Arabia. It is abbreviated as ر.س SAR, or SR (Saudi Arabian Riyal/Saudi Riyal). It is subdivided into 100 halalas (Arabic: هللة Halalah). The currency is pegged to the US dollar at a constant rate of exchange. [2]
In 1974 MOL established the Saudi Arabian Shipping Co., Ltd. (SASCO) and Arabian Marine Operation Co. Ltd. (AMOCO) as joint ventures with the prince of Saudi Arabia in Jeddah. SASCO is the shipowner, while AMOCO manages tanker operations. MOL hoped that this joint venture would give it an advantageous status in any future nationalization of oil ...
The Ministry of Human Resources and Social Development has developed an employment strategy that was approved by the Saudi Council of Ministers in 2009. This strategy is based on providing sufficient job opportunities in terms of number, and appropriate in terms of pay, leading to full employment of Saudi human resources, and achieving a ...
De facto exchange-rate arrangements in 2022 as classified by the International Monetary Fund. Floating ( floating and free floating ) Soft pegs ( conventional peg , stabilized arrangement , crawling peg , crawl-like arrangement , pegged exchange rate within horizontal bands )
The solution has 1 mole or 1 equiv Na +, 1 mole or 2 equiv Ca 2+, and 3 mole or 3 equiv Cl −. An earlier definition, used especially for chemical elements , holds that an equivalent is the amount of a substance that will react with 1 g (0.035 oz) of hydrogen , 8 g (0.28 oz) of oxygen , or 35.5 g (1.25 oz) of chlorine —or that will displace ...
where A and B are reactants C is a product a, b, and c are stoichiometric coefficients,. the reaction rate is often found to have the form: = [] [] Here is the reaction rate constant that depends on temperature, and [A] and [B] are the molar concentrations of substances A and B in moles per unit volume of solution, assuming the reaction is taking place throughout the volume of the ...
Molar concentration or molarity is most commonly expressed in units of moles of solute per litre of solution. [2] For use in broader applications, it is defined as amount of substance of solute per unit volume of solution, or per unit volume available to the species, represented by lowercase : [3]
One way to write the van der Waals equation is: [8] [9] [10] = where is pressure, is temperature, and = / is molar volume. In addition is the Avogadro constant, is the volume, and is the number of molecules (the ratio / is a physical quantity with base unit mole (symbol mol) in the SI).
