Question 33 Not yet anawered Merked out of 20.00 Flequation 1. A sample of the gaseous anesthetic cyclopropane, with a volume of 425 mL at a temperature of 27°C, is cooled at a constant pressure to 20°C. What is the new volume, in milliliters, of the sample? 2. The colorless, odorless, tasteless gas carbon monoxide, CO, is a by-product of incomplete combustion of any material that contains the element carbon. Calculate the volume, in liters, occupied by 1.52 moles of this gas at 0.99 atm pressure and a temperature of 65°C. Use 3.
