Chemistry Molarity help needed
Explain why, in terms of intermolecular forces, as n increases for the molecule CH3(CH2)nOH, the solubility of the molecule in hexane increases. Calcium nitrite (Ca(NO2)2/ MM = 132.1 s/mol) is used as a corrosion inhibitor in lubricants. What is the molality of a solution prepared by dissolving 18.5 g of calcium nitrite in 83.5 g of distilled water (MM = 18.02s/mol)? I have a 17.0% by mass solution of sodium acetate, CH3COONa (MM = 82.0 s/mol) in water (MM = 18.02 s/mol). What is the molarity of this solution? The density of the solution is 1.09 s/mL.
