Sparking is produced in a mixture 20 mL O_(2) , and 20 mL CO, the volume of the gaseous mixture obtained will be

Calculate the amount of hydrogen peroxide present in 10 mL of 25 volume solution of H_2O_2

10 " mL of " a gaseous organic compound containing C, H and O only was mixed with 100 " mL of " O_(2) and exploded under condition which allowed the H_(2)O formed to condense. The volume of the gas after explosion was 90 mL. On treatment with KOH solution, a further contraction of 20 mL in volume was observed. The vapour density of the compound is 23. All volume measurements were made under the same condition. Q.The volume of unreacted O_(2) is
