When working with aqueous solutions, it is common to assume that the density of water is 1.00 g/mL. Therefore, it is common to equate 1 kilogram of water with 1 L of water. Consequently, 1 ppm corresponds to 1 mg/L and 1 ppb corresponds to 1 μg/L.
5-Methylchrysene is a polycyclic aromatic hydrocarbon (PAH) with a molecular weight of 242.3 g/mol and melting point of 117.5 °C (243.5°F). The chemical formula of it is C 19 H 14 . It has a vapour pressure of 0.00000025 mmHg.
The MG L-type is a sports car that was produced by the MG Car company in 1933 and 1934. This 2-door sports car used a smaller version of the 6-cylinder overhead camshaft , crossflow engine which now had a capacity of 1086 cc with a bore of 57 mm and stroke of 71 mm and produced 41 bhp (31 kW) at 5500 rpm.
The tonne (t) is an SI-compatible unit of mass equal to a megagram (Mg), or 10 3 kg. The unit is in common use for masses above about 10 3 kg and is often used with SI prefixes. For example, a gigagram ( Gg ) or 10 9 g is 10 3 tonnes, commonly called a kilotonne .
In a recent Newsweek article, Alex Beene, a financial literacy instructor at the University of Tennessee at Martin, said, “Many in the real estate business are elated with a Trump victory, and ...
Donald Trump’s pick for defense secretary, Pete Hegseth, said gay people should be able to serve in the US military in an apparent shift from his previous stance on the issue.
An aqueous solution containing 120 mg NaHCO 3 (baking soda) per litre of water will contain 1.4285 mmol/l of bicarbonate, since the molar mass of baking soda is 84.007 g/mol. This is equivalent in carbonate hardness to a solution containing 0.71423 mmol/L of (calcium) carbonate, or 71.485 mg/L of calcium carbonate (molar mass 100.09 g/mol).
By that reasoning, Miami’s playoff hopes are toast barring an unexpected blowout loss for a team like Penn State or Georgia in their conference title games on Saturday that somehow drops one or ...
