A student forgot to add the reaction mixture to the round-bottomed flask at 27o C but instead he/she placed the flask on the flame. After a lapse of time, he realised his mistake, and using a pyrometer he found the temperature of the flask was 477° C. What fraction of air would have been expelled out?
