The water content of an 875.4-mg sample of cheese was determined with a moisture analyzer. What is the %w/w H2O in the cheese if the final mass was found to be 545.8 mg?
mass of H2O = 875.4 mg - 545.8 mg = 329.6 mg
%w/w H2O = mass of water *100/total mass
= 329.6*100 / 875.4
= 37.65 %
Answer: 37.65 %

A technician you supervise is to determine the moisture content of a food product by the Karl Fischer method. Your technician wants to know what is this "Karl Fischer Reagent Water Equivalence" that is used in the equation to calculate percentage of moisture in the sample, why is it necessary, and how it is determined. Give the technician your answer.
B. The moist weight of 0.028 m3 of a soil is 52 kg. The moisture content and the specific gravity of the soil solids are determined in the laboratory to be 11% and 2.7 , respectively.

To determine content of chloride in cheese, a cheese sample is treated with 5.00ml of 0.1 mol/L silver nitrate solution, several milliters of concentrated nitric acid and potassiu permanganate solution are added. The filtrate is then diluted to the mark in a volumetric flask and titrated by a back titration with standard solution of potassium thiocyanate (Volhard method) (a). What is the role of potassium permanganate solution? Could we add potassium permanganate solution before adding silver nitrate solution? Why? (b)....

Consider a pile of green wood chips at 60% moisture content (wet basis) and weighing 1 t. What is the oven-dry mass of biomass in the pile? The biomass has a heat of combustion of 16 MJ per oven-dry kg. This is the 'gross calorific value' corresponding to the heat output in a reaction of the type [CH,O]+O2 CO2(gas) +H2O(liq) The net calorific value (or 'lower heating value') is the heat evolved when the final water is gaseous; in practice...
The zinc content of a 1.45 g ore sample was determined by dissolving the ore in HCl, which reacts with the zinc, and then neutralizing excess HCl with NaOH. The reaction of HCl with Zn is shown below:Zn+2HCL--ZnCl2+H2The ore was dissolved in 150 mL of 0.600 M HCl, and the resulting solution was diluted to a total volume of 300 mL. A 20.0 mL aliquot of the final solution required 8.48 mL of 0.508 M NaOH for the HCl present...
The zinc content of a 1.23 g ore sample was determined by dissolving the ore in HCI, which reacts with the zinc, and then neutralizing excess HCl with NaOH. The reaction of HCI with Zn is shown below. Zn(s)-2HCl(aq) → ZnCl2(aq)-H,(g) The ore was dissolved in 150 mL of 0.600 M HCI, and the resulting solution was diluted to a total volume of 300 mL. A 20.0 mL aliquot of the final solution required 9.19 mL of 0.529 M NaOH...
