There's 1 drink (and you are asked to determine the glucose concentration in the drink in the units of g/100mL. (Why these units? Well, once you have the concentrations in g/100mL you will be able to compare your values with the nutritional values given on the drink bottles’ labels). The sample of the drink was diluted 1/100 (i.e. by a factor of 100). This was an essential step in the method because, without it, the machine used to analyse the glucose concentration (spectrophotometer) would have given an error as the concentration would have been too high for accurate detection. What this means for you is that the dilution factor will need to be taken into consideration in your calculations (remember the aim is to calculate the concentration in the original drink and not in the diluted drink). You measured the concentration of their diluted drink using the spectrophotometer and their results were provided to them in the units mM (millimolar). Glucose Concentration in mM of drink =…

A solution containing 100 lbm KNO 3/100 lbm H 2O at 80°C is fed to a cooling crystallizer operated at 25°C. Slurry from the crystallizer (KNO3 crystals suspended in saturated solution) is fed to a filter, where the crystals are separated from the solution. Use the solubility data in Figure 6.5-1 to determine the production rate of crystals (lbm/lbm feed) and the solid-to-liquid mass ratio (lbm crystals/lbm liquid) in the slurry leaving the crystallizer.
An aquifer contaminated with petroleum is found to have the following component concentrations at a particular site: benzene 158 ppm toluene 124 ppm ethylbenzene 91 ppm xylene 45 ppm n-heptadecane 161 ppm pristane 84 ppm Provide an estimate for the age of the spill at this site using (a) BTEX ratio and (b) nC17:Pr ratio. Show your calculations and use units throughout. Give proper s.f. for the answer.

The %purity of a powdered crude sample of Na2CO3 containing only inert impurities is to be determined by reacting 225.0 mg of the crude sample to 10.0 mL of 3.00 M HCl solution, and bubbling the resulting CO2(g) product in water that is at exactly 29 °C. After the reaction has completed, the level of the liquid inside the eudiometer rests 4.30 cm above the water level in the beaker. The graduation on the eudiometer indicates that the trapped gas is 44.37 mL. The experiment was done under a barometric pressure of 755.2 torr. a. How many moles of CO2 were collected? b. What is the percent purity of the sample? Round off to the nearest whole number

100 g of soil is leached with a strong solution of Calcium chloride such that all the exchange sites are occupied by Ca2+. The soil is subsequently leached again with a strong solution of magnesium chloride. It is determined that the resulting 100 mL leachate contains 5000 mg of Ca2+. What is the soil CEC (cmolc/kg)? The atomic wt. of Ca is 40 g/mol.please answer in word don't image upload thank you.
Gypsum (CaSO4) is one of common precipitants in brackish water desalination processes. CaSO4 ⇋ Ca2+ + SO42- Ksp = 10-4.6Assume a water containing: [Ca2+] = 10-2.1 M; [SO42-] = 10-3.2 M.(a) Find Qsp or IAP for the given water. (b) Find the solubility index (SI) and determine whether CaSO4 is under, super, or at saturation in the water.
