When heated to a temperature of 311 "C, formic acid, which has the molecular formula of HCOOH, will decompose in a first-order reaction with the rate constant of 3.80 x 10-3 g1. How long will it take for 3/4 of a sample of HCOOH to decompose? The numbers used here are not the actual values as they have been changed for purposes of this exam. Report your answer in seconds, with no units. Give at least 3 significant digits. For the purposes of answering this question, if you get an answer such as 150, consider the last O as one of these three digits.
