Webb11 apr. 2024 · The pseudo-first-order kinetic equation was well fitted (R 2 = 0.992) (Table 2), indicating that the adsorption process of BC-HA on Ni (II) may be affected by surface physical adsorption. WebbNow we have found the theoretical purity. We need to calculate the percentage of purity. We do this by using the formula from above: MASS of USEFUL PRODUCT % purity = in TOTAL MASS of SAMPLE x 100 % purity = 2.49g 2.5212g x 100 % purity = 98.8 % (3 significant figures) Now since you've learnt all of these, it's time to put your skills to the …
Webb14 apr. 2024 · Generally, 0.1 μm–100 μm is called the micrometer scale, and 1 nm–100 nm is called the nano scale, so 1 nm–100 μm is defined as the micro-nano scale.As shown in Fig. 1, the scale range spans five orders of magnitude from the macro scale to the molecular scale, and the traditional fluid mechanics theory will change greatly. 5 5. WebbHowever, a free Theoretical Yield Calculator is used for chemical reactions that compute the theoretical yield according to the theoretical yield formula. Example: Dissolve 2.0 g of the unknown monobasic acid sample in 100 ml of water. A 20 ml portion of this solution requires 15 ml of 0.12 M NaOH solution to reach the titrations equivalence point.
