Magnesium is a mineral found in a wide variety of foods. Inside of our bodies we mostly find magnesium in our bones (60-65%), in our muscles (25%) and in other cell types and body fluids. Magnesium cannot be made in our body like all minerals, which is why we need to take it in through magnesium-rich foods.
The Brinell hardness number (HB) is the load divided by the surface area of the indentation. The diameter of the impression is measured with a microscope with a superimposed scale. The Brinell Hardness Number is computed from the equation: P is the applied load of 3000, 1500, or 500kg.
Gravels and Substrates. CaribSea, Freshwater, Instant Aquarium, Moonlight Sand density is equal to 1601.85 kg/mÂ³ or 100 lb/ftÂ³ with specific gravity of 1.60185 relative to pure water. Calculate how much of this gravel is required to attain a specific depth in a cylinder, quarter cylinder or in a rectangular shaped aquarium or pond. Gallium weigh(s) 5.904 gram per (cubic centimeter) or 3.413 ounce per (cubic inch) [ weight to volume | volume to weight | density ].
