CH301(4) Notes part 1 answers 1. Calculate the molarity of a solution that contains 12.5 g of sulfuric acid in 1.75 L of solution. Note here we must covert moles to grams: 42SOH0728.0LSOHmol0728.0SOHg98.1SOHmol1nsol'L75.1SOHg12.5nsol'LSOHmol?Mu2. Determine the mass of calcium nitrate required to prepare 3.50 L of 0.800 M Ca(NO3)2. 23)Ca(NOg459)Ca(NOmol1)Ca(NOg164L)Ca(NOmol0.800L50.3)Ca(NOg?uu Note: you would NOT add this to 3.5L of water, but use the method shown previously: add sufficient distilled water to the dissolved solid to make the volume 3.5L Dilution example 1: We take 5ml of a 0.1M solution of HCl and place it in a 100ml volumetric flask, and dilute to the mark with distilled water. What is the concentration of the new HCl solution?
