In subject area: Pharmacology, Toxicology and Pharmaceutical Science Microfluidics, or “labs on a chip,” deals with the behavior, specific control, and manipulation of a fluid that is geometrically forced into a small, typically submillimeter scale at which capillary penetration controls mass transpor...
1.35 mol/L的 NaCl溶液的质量分数是多少 假设溶液体积是1000 mL,那么溶液质量 = 1000 ÷ 1.05 = 952.38 g 溶质质量 = 1.35 × (23+35.5) = 78.975 g 质量分数 = 78.975 ÷ 952.38 = 0.0829 = 8.29
