Calculating protein concentration: I understand that concentration is g/ml, but how can grams of protein divided by ml of the fluid equal percent amino acid solution? (Regarding the example calculation: 88 g / 1509 cc = 0.058 g/ml ... then how can it be 5.8% amino acid solution??) "Determine protein concentration. Subtract volume of lipid from fluid requirement to determine remaining fluid needs. Divide protein requirement (in grams) by remaining fluid requirement and multiply by 100. This gives you the...
Given that pK1 = 3.0 and pK2 = 8.0 for an amino acid X. Total concentration of amino acid X in solution is 10 mM. Calculate the concentrations of protonated form (P), dipolar form (Z) and de-protonated form (D) of amino acid X at pH 2, and 10.

Нас .Н20 Na+ H2N What is the pH of the salt solution? 20-mL aliquot of would result, making sure to label at least four sets of values on the graph. a ior itrated with 0.100 M b on curve that...
A chemist needs to determine the concentration of a sulfuric acid solution by titration with a standard sodium hydroxide solution. He has a 0.1659 M standard sodium hydroxide solution. He takes a 25.00 mL sample of the original acid solution and dilutes it to 250.0 mL. Then, he takes a 10.00 mL sample of the dilute acid solution and titrates it with the standard solution. The endpoint was reached after the addition of 11.76 mL of the standard solution. What...
A solution of an unknown monoprotic acid has a mass concentration of 2.8 g L-1. A titration was performed and the concentration was found to be 0.038 mol L-1. What is the molar mass of the unknown monoprotic acid in solution?
A solution of tartaric acid is prepared of concentration 1.2174 g L -1 and it is found that 50.0 ml of the solution requires 21.48 mL of 3.78 × 10-2 mol L -1 sodium hydroxide for complete neutralization. The formula of tartaric acid is C4H6O6 and its relative molecular mass is 150.2. Calculate how many of the hydrogens in a molecule of tartaric acid are ionised in aqueous solution.
