A) zinc = 0.04g\L I need the answer for (B) please! 3.) Metal concentrations in wastewater sludges are often expressed in terms of grams of metal per kilogram of total dry solids. A wet sludge has a solids concentration of 200,000 mg/L, and 8000 mg/L of these solids are zinc. a. What is the concentration of zinc as g Zn g dry solids? b. If this sludge is to be applied to farmland and spread on pastures used by cows,...
I have 5 mg of simvastatin as my stock solution. I want to make concentrations of 25ul. How can I do it
Groundwater has the following concentrations: O2 = 8 mg/L NO3- = 15mg/L SO42- = 35 mg/L In a BTEX contaminant plume in the same aquifer, the dissolved iron concentration is 20 mg/L. Neglecting methanogenesis, what is the assimilative capacity of the aquifer for benzene?
1. A wastewater sample contains 7.4 mg P/L PO, and 4.5 mg P/L P,0*. a. Calculate the total phosphorus as mg PL b. Find the concentrations of Poland P0,* in wastewater as mg PO/L and mg P.0. L, respectively.
The blood concentration is given in mg/dL. Calculate the approximate concentrations of blood glucose in mM. The molecular weight of glucose is 180 g/mol. There are 10 dL in 1 L. Blood glucose (mg/dL) To download image, click here In the experiment above, blood samples were taken from wild type (WT, white bar) or double knockout mice (DKO, black bar) and glucose in the blood was measured. In this experiment mice always have a supply of food pellets that they...
6.22 A sample of water has the following concentrations of ions: mg/l 40.0 10,0 mg/l 110.0 67.2 11.0 Cations Anions HCO; so Cl Mg Na " 7.0 (a) The concentration (expressed as mg/L) of slaked lime (CalOH)l added to the water to achieve the maximum practical softness. (b) The concentration (expressed as mg/L) of soda ash (Na,CO,) added to achieve the maximum practical softness.
For equilibrium at 25 oC with the atmosphere, what are the aqueous concentrations of N2 (mg/L), O2 (mg/L) and CO2 (mol/L) in natural water? Example: N2 : 0.79 atm O2 : 0.21 atm CO2 : 10-3.38 atm
