1. I need to prepare a solution of 0.2 L 0.4 M then determine how many cm^3 of a solution of H2SO4 (sulfuric acid) 80.0% (density = 1.727 g/mL) should be diluted with H2O? Also also explain what's the pH of this solution if I combine 800 cm^3 of water and 6grams of sodium hydroxide?
Explain would the calculated molarity of NaOH be too high or too low If the KHP weighed in your experiment today was contaminated with some unknown inert substance.
