The concentrations of metals in seawater range over 15 orders of magnitude from sodium, the most abundant cation, at a concentration close to 0.5 mol kg21 to iridium at a concentration as low as 0.5 ... TīmeklisSulfur hexafluoride is an inert perfluorine, routinely detectable in sea water at ∼0.01 fmol kg −1 by electron-capture gas chromatography (1 fmol=10 −15 mol). At room temperature and pressure SF 6 is a gas, but it forms a dense ( ρ =1880 kg m −3) liquid at pressures exceeding 20 bar. It is extremely stable in the environment and, other ...

Tīmeklis2024. gada 7. sept. · 单纯谈mol与mg的换算没有意义。 摩尔这个单位要结合具体微粒才有意义。 例如1mol氟离子代表NA个氟离子,NA为阿伏加德罗常数,约为6.022e23。 1mol氟离子的质量,大约等于19.00g,数值等同于其原子量。 换算就不用我教了吧。 发布于 2024-09-07 07:03 赞同 2 添加评论 分享 收藏 喜欢 收起 Ravenclaw 生化制药 … Tīmeklis2024. gada 13. febr. · I need to convert a rare earth element in seawater from pmol/kg to ppm. I've tried the following conversion method but am unsure whether it's correct. Please can someone look over? Lutetium= 174.9668 (MW) Lu = 0.4025 pmol/kg = 0.4025 x 1E-9 = 4.025E-10 mmol x 174.9668 g = 7.0424E-11 g/kg = 7.0424E-11 * … TīmeklisThe limit of detection for SF6 is even more sensitive at 0.05 x 10-15 moles per kilogram of water (fmol kg-1).
