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: 42 SO H 0728 . 0 L SO H mol 0728 . 0 SO H g 98.1 SO H mol 1 n sol' L 75 . 1 SO H g 12.5 n sol' L SO H mol ? M u 2. Determine the mass of calcium nitrate required to prepare 3.50 L of 0.800 M Ca(NO 3 ) 2 . 23 ) Ca(NO g 459 ) Ca(NO mol 1 ) Ca(NO g 164 L ) Ca(NO mol 0.800 L 50 . 3 ) Ca(NO g ? u u 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?
