The EPA limit for manganese in drinking water is 0.05 mg per L of solution. What is this concentration of manganese in mass %, ppb, and molarity? Assume the solution has the same density as water. Use "E" for scientific notation; e.g. 0.001 would be entered 1E-3 mass % ppm molarity = 2.jpg 3.jpg Open file 4.jpg Open file 5.jpg Open file Open file file 99+ op

Calculate the volume of stock glucose solutions (2.5 % and 15%) that need to be used to prepare 800 mL of glucose solution with a concentration of 13%. In this case % refers to the grams of glucose per 100 mL of water. V1= volume of stock solution with concentration C (2.5%) V2= volume of stock solution with concentration C2 (15 %) You need to determine V, and V2 in mL

What volume of ethanol (density = 0.7893 g/cm³) should be added to 450. mL of water in order to have a solution that freezes at -15.0°C? Assume the density of water is 1.0 g/mL. (For water, K₁= 1.86 °C/m.) Select one: O a. 371 mL O b. 470 mL O c. 212 mL O d. 132 mL O e. 167 mL (Please type answer with explanation).

Use the solubility graph to answer the following question. Name the type of solution if 750 g of NaNO3 was placed in 600 mL of the water at 50 °C. Solubility Curves KI Solubility (g/L of solvent) 1400 1300 1200 1100- 1000 900 800 700- 600 500 400 300 200 100 0 polyunsaturated unsaturated saturated 0 supersaturated -HCI saturated with excess solute SO₂ NaNO3 -KNO₂ NHẠCH KCI -KCIO3 NaCl NH3 10 20 30 40 50 60 70 80 90 100 Temperature (°C)

How does a solution become supersaturated?   Dissolve lots of solvent in it.   Dissolve a little solute in it.   Dissolve more solute than normal while heating the solution.   Dissolve less solute than normal while cooling the solution.
