20mL of a mixture of CO and H2 were mixed with excess of O2 and exploded and cooled. There was a volume contraction of 18mL. All volume measurements corresponds to room temperature (27C) and one atmospheric pressure. Determine the volume ratio V1:V2 of CO and H2 in the original mixture.(a) 1:2 (b) 3:2(c) 2:3 (d) 4:1 |
