— "Values ranging from 21.3 to 21.5 gm/cm 3 at 20 °C have been reported for the density of annealed platinum; the best value being about 21.45 gm/cm 3 at 20 °C." 21.46 g/cm 3 — Rose, T. Kirke. The Precious Metals, Comprising Gold, Silver and Platinum .
Spectral lines of chlorine: Other properties; ... Density [kg/m3 at s.t.p.] Density [g/cm3 near room temperature] [g/cm3 near r.t.], #2 [g/cm3 near r.t ...
Density (at STP) 3.2 g/L ... Chlorine is a chemical element; ... The chlorine produced is available in cylinders from sizes ranging from 450 g to 70 kg, as well as ...
Depending on the method, a varying amount of chlorine is introduced into the polymer allowing for a measured way to fine-tune the final properties. The chlorine content may vary from manufacturer to manufacturer; the base can be as low as PVC 56.7% to as high as 74% by mass, although most commercial resins have chlorine content from 63% to 69%.
Density: 1.3266 g/cm 3 (20 °C) [2] ... 1.25 g/kg (rats, oral) ... DCM is produced by treating either chloromethane or methane with chlorine gas at 400–500 °C. At ...
The standard unit is the meter cubed per kilogram (m 3 /kg or m 3 ·kg −1). Sometimes specific volume is expressed in terms of the number of cubic centimeters occupied by one gram of a substance. In this case, the unit is the centimeter cubed per gram (cm 3 /g or cm 3 ·g −1 ).
The relative density of gases is often measured with respect to dry air at a temperature of 20 °C and a pressure of 101.325 kPa absolute, which has a density of 1.205 kg/m 3. Relative density with respect to air can be obtained by =, where is the molar mass and the approximately equal sign is used because equality pertains only if 1 mol of the ...
Density: 3.66 kg/m 3 at 15 ... because of its relatively low ozone depletion potential of 0.055, [4] among the lowest for chlorine-containing haloalkanes. However ...
