50 ml of a mixture consisting of 0.019 m cerium (iv) and 2.7 m h2so4, or sulfuric acid. begin by preparing 100 ml of 2.7 m h2so4 using the available solution of 42.3% w/w h2so4. this concentration unit, which may be less familiar to you, is a weight-to-weight percent (100.0 g of the solution contains 42.3 g of h2so4). the density of 42.3% w/w h2so4 is 1.25 g solution/ml solution. using a graduated cylinder, measure out the correct volume of 42.3% w/w h2so4 and slowly add it to a 100-ml volumetric flask that already contains approximately 25 ml of deionized water.
