The percentage of crude protein base on dry matter. ii. The percentage of crude protein base on natural (fresh) material. iii. The percentage of crude protein base on organic matter, when crude ash in the feedstuff is 0.3 g.please help this is my 4th time posting this and i havent gotten a correct answer. Please actually draw the graph out. A newly discovered enzyme, MBCase, cleaves carbon-carbon bonds of vicinal alcohol; The kinetic parameters were measured for 1.0 nM Of MBGase and determined to be a Km = 10 nM and a kcat = 100 s-1 a.) Sketch the graph out as a double-reciprocal plot (Lineweaver-Burke Plot) and label: -the axes (with units) -the point on the curve that can be used to determine Km -the point on the curve that can be used to determine Vmax-Describe the equations for the measurement of mass and mole fraction in dimensionless concentration.

- Comment on the precision of your data from the prelab. Specifically: a) What assumptions were you making about the total volume of your standard solutions? b) What was the limiting piece of equipment for your volume measurements?c) How many significant figures should your concentration data have?Pls do fast within 5 minutes and i will give like for sure Solution must be in typed form To plan a liquid–liquid extraction we need to know the solute’s distribution ratio between the two phases. One approach is to carry out the extraction on a solution that contains a known amount of solute. After the extraction, we isolate the organic phase and allow it to evaporate, leaving behind the solute. In one such experiment, 1.235 g of a solute with a molar mass of 117.3 g/mol is dissolved in 10.00 mL of water. After extracting with 5.00 mL of toluene, 0.889 g of the solute is recovered in the organic phase. If we extract 20.00 mL of an aqueous solution that contains the solute using 10.00 mL of toluene, what is the extraction efficiency?A solution of common salt in water is prepared by adding 50kg of salt to 200kg of water tomake a liquid density of 1250kg/m3. Calculate the concentration of salt in this solution as a: i) Weight(w/w)fraction (Ans: weight fraction 20%)
