What is the specific gravity of argon?

Question 1: What is the specific gravity of argon? Specific gravity of argon: gas density (0℃,101.325kpa):1.745438+0kg/m3, that is, per liter 1.745438+0 g.

Argon: national standard number 220 1 1, CAS number 7440-37- 1, molecular formula ar, molecular weight 39.95, colorless and odorless inert gas; The vapor pressure is 202.64 kpa (-179℃); Melting point-189.2℃; Boiling point-185.7℃ solubility: slightly soluble in water; Density: relative density (water =1)1.40 (-186℃); Relative density (air =1)1.38; Stability: stability; Danger sign 5 (incombustible gas); Main uses: Used for gas filling and arc welding of stainless steel, magnesium and aluminum bulbs, that is, "argon arc welding". Question 2: What is the specific gravity of air and argon? Wow, the standard air density is 1.293kg/m3, and argon is 1.784kg/m3. Question 3: What is the density of argon at 0℃ and 1atm? In the standArd state (0℃ and 1atm), the density of argon (ar) is 40. Question 4: What is the density under the gas standard? It is out of the question. Many logistics companies can check computers, including railways.

The Dell machines we bought here are all delivered directly from Xiamen to Shijiazhuang, which seems to be called Da What Tong, and the service is very good. Ask more logistics companies and find a bigger one. Although it is expensive, it also guarantees the goods.
