Calculate solution concentration A solution consists of 44.3 g of ammonia, NH3, and 103.7 g water. (a) Calculate the weight percent, the molality, and the mole fraction of NH3 in the solution. % weight percent = molality = mole fraction = m (b) The solution volume is 166 ml. Calculate the molarity of NH3 in the solution. molarity M The EPA's secondary standards for contaminants that may cause cosmetic or aesthetic effects in drinking water suggest an upper limit of 250 mg/L for sulfate ion. If 3.77x104 liters of water in a storage tank contains 19.6 grams of s042, what is the contaminant level in ppm? in ppb? Is this level acceptable based on EPA guidelines? ppm ppb Step by Step Solution
