Pretend you are an environmental chemist attending a merienda in Malacanang with influential lawmakers. While discussing your research with a senator, you realize he has no idea what you are talking about in terms of air mixing ratios. Please describe to him how much a ppt, a ppm, and a ppb are in terms of 5 gallons of water (the bottles placed on top of water dispensers) and drops of arnibal (syrup used in taho). Estimates are required.
