  2. Mass concentration (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_concentration_(chemistry)

    In chemistry, the mass concentration ρi (or γi) is defined as the mass of a constituent mi divided by the volume of the mixture V. [1] For a pure chemical the mass concentration equals its density (mass divided by volume); thus the mass concentration of a component in a mixture can be called the density of a component in a mixture.

  3. Fuel oil - Wikipedia

    Viscosity also increases with number, and the heaviest oil must be heated for it to flow. Price usually decreases as the fuel number increases. [7] Number 1 fuel oil is a volatile distillate oil intended for vaporizing pot-type burners and high-performance/clean diesel engines. [8]

    Territorial waters and exclusive economic zone of the Philippines. The Philippines is an archipelagic state whose over 7,000 islands of roughly 300,000 square kilometres (120,000 sq mi) [1] are surrounded by 36,289 kilometres (22,549 mi) of coastline [2]: 15 supporting a large coastal population.

  5. Mass fraction (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Mass_fraction_(chemistry)

    Mass fraction (chemistry) In chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. [1] Expressed as a formula, the mass fraction is: Because the individual masses of the ingredients of a mixture sum to , their mass fractions sum to unity:

  6. Parts-per notation - Wikipedia

    en.wikipedia.org/wiki/Parts-per_notation

    In science and engineering, the parts-per notation is a set of pseudo-units to describe small values of miscellaneous dimensionless quantities, e.g. mole fraction or mass fraction. Since these fractions are quantity-per-quantity measures, they are pure numbers with no associated units of measurement.

  7. Olive oil acidity - Wikipedia

    en.wikipedia.org/wiki/Olive_oil_acidity

    As defined by the European Commission regulation No. 2568/91 and subsequent amendments, [1] the highest quality olive oil (extra-virgin olive oil) must feature a free acidity lower than 0.8%. Virgin olive oil is characterized by acidity between 0.8% and 2%, while lampante olive oil (a low quality oil that is not edible) features a free acidity ...

    Territorial waters and exclusive economic zone of the Philippines. The Philippines is an Archipelagic state whose over 7,000 islands [1] with their large coastal population [2]: 2 are surrounded by waters including 2,263,816 square kilometres (874,064 sq mi) of exclusive economic zone and 679,800 square kilometres (262,500 sq mi) of territorial sea [3]: 1 surrounding 36,289 kilometres (22,549 ...

    The 2020 Russia–Saudi Arabia oil price war resulted in a 65% decline in global oil prices at the beginning of the COVID-19 pandemic. [110] [111] In 2021, the record-high energy prices were driven by a global surge in demand as the world recovered from the COVID-19 recession.
