A common industrial unit for expressing the concentration of hydrogen peroxide

1) A common industrial unit for expressing the concentration of hydrogen peroxide is to state the relative volume of oxygen gas at 0 (degrees Celcius) and 1atm produced per volume of hydrogen peroxide solution that decomposes.This is how the units works:Example #1: When 1L of a V20 hydrogen peroxide solution decomposes: 20L of oxygen gas at 0 (degrees Celcius) and 1atm is producedExample#2: when 1L of a V22 hydrogen peroxide solution decomposes: 22L of oxygen gas at o (degrees Celcius) and 1 atm is produced.a. What volume of oxygen gas at 0 (degrees Celsius) and 1atm will be produced with 1L of V27 solution is decomposed?b. Calculate the concentration of V27 solution in units of molarityc. Calculate the concentration of a V27 solution in units of (m/v) percent.2) If 0.56g KI is used to decompose 6.0mL of 3.0% H202 solution what mass of KI will be present after all the H202 decomposes?Does the exact mass of KI matter?
