1. The following data are from total and volatile solids tests on a wastewater. Calculate the total and volatile solids concentration in mg/L. Weight of empty dish = 68.942 g Weight of dish + dry solids = 69.053 g Weight of dish + ignited solids = 69.003 g Volume of wastewater sample = 100 mL
a dilution is needed to prepare a standard of 10 mg Zn/L from 0.5g Zn/L. To carry out the dilution we have the following available bulb pipettes: 1ml,2ml,5ml,10ml,20ml and 25 ml and the following volumetric flask: 50ml,100ml,250ml,500ml. which bulb pipette and which corresponding volumetric flask you would choose to carry out the dilution?
You are analyzing the effluent from a lotion plant for parabens using HPLC. You have a working standard solution with a concentration of 59.4 ppm which returned a Peak Height of 10,164 and Peak Area of 5,315. You take 44.4 L of the water sample and concentrate it to 0.3 L and analyze this solution. The Peak Height is 9,119 and the Peak Area is 6,320. What is the concentration of parabens in the effluent of the plant in mg/L to two decimal places.
One milliliter (mL) of pure water has a mass of 1 gram (g). You add 100 mL of water and 100 mL of an organic solvent to a separatory funnel, shake, and let settle. There will be two layers of liquids. Select the one solvent listed below that will result in the water layer being the top layer. For each solvent, density (d) is given in g/ml. Toluene (d = 0.86) Tetrahydrofuran (d = 0.88) water is never the top layer Methylene chloride (d = 1.33)
