我也觉得你写错了,应该是equivalent weight中文解释为:当量当量:当量指与特定或俗成的数值相当的量;化学专业用语,用作物质相互作用时的质量比值的称谓。化学专业用语:在任何化学反应中,物质的质量比等于它们的当量比。泛 当量指化学方面的当量术。诸如 当量、克当量、当量浓度、酸碱盐当量、电化当量 等。根据定组成...
A solution contains 30 mg of NaCl (table salt) per 400 mL of solution. Express the solution in terms of milliequivalents per liter (mEq/L). (Note: the molecular weight of NaCl is 58.44 g/mol.) •This time, the solute has a valence of 2, as NaCl separates into Na+and Cl-. The...
In the laboratory, NaCl, tap water and distilled water are used for measuring conductivity and ESDD. In addition, different sizes of glass plates are used as an insulating medium. A conductivity-measuring instrument (Cond 300i) is used to measure the conductivity of the salt-solution. Based ...
Weigh 0.5711 g Na2HPO4 (Mr 141.96 g/mol), 0.24 g KH2PO4 (Mr 136.09 g/mol), 8 g NaCl (Mr 58.44 g/mol), and 0.2 g KCl (Mr 74.55 g/mol) and dissolve in ~900 mL distilled water. Adjust to pH 7.4 with 1 M HCl and make up to 1000 mL with distilled water. • Oxidi...
At the molecular level, the structures of NaCl solutions are determined by the arrangement of the water molecules populating in ions’ various solvation shells. In the FSS, water is bonded to both the ions and waters in the second shell. The nature of the interaction is determined by the ele...

Just before the study end, GFR was estimated in conscious mice using the transcutaneous decay of retro-orbitally injected FITC-sinistrin (10 mg/100 g body weight dissolved in 0.9% NaCl), as previously described58. Plasma cystatin C was also measured by ELISA at the study end (BioVendor...
