Your are almost correct.😊 If the actual half-life (50%) was 1.5 days, then 25% would be 2.25 days. So the high volatilization of vinyl chloride and it’s short half life allows for it to dissipate in roughly 2 days. Could be slightly more but we are splitting hairs at that point.

If it's like radioactivity, then it would be 3 days. 1.5 days to reduce by 50% and then another 1.5 days to reduce by another 50% to 25%.
