Begin by preparing 100 mL of 2.7 M H2SO4 using the available solution of 42.3% w/w H2SO4. This concentration unit is called a weight-to-weight percent, meaning there are 42.3 g of H2SO4 in 100.0 g of the solution. The density of 42.3% w/w H2SO4 is 1.25 g solution/mL solution. Calculate the volume, in mL, of 42.3% w/w H2SO4 that is required to make 100 mL of 2.7 M H2SO4. Hint: you should determine what molarity 42.3% w/w H2SO4 is first. Using a graduated cylinder, slowly add the H2SO4 to a 100- mL volumetric flask that already contains approximately 25 mL of deionized water. Dilute to volume with deionized water and mix thoroughly
