When you calculate the molarity and molality of the EDTA solution are the values very similar or not? Explain if this is what you might expect for a dilute aqueous solution with a density very close to 1.0 g/mL.
A chemist was called to an abandoned aspirin factory to determine the contents of a badly corroded vat. Knowing that two salvage workers had become ill from breathing the fumes
You are designing a drier that must evaporate 200 lb/h of H2O from sludge by using air. Air at 70°F and 50% relative humidity is drawn into the drier and it leaves at 140F and 70% relative humidity. How much volume of dry air needs to be used for ..
