Wherever calculations are involved, show answers with appropriate number of significant figures. Include units wherever necessary. Show your work in the spaces below questions; just the final answers, even when correct, will not earn much credit. 1. At 27°C and 720 Torr, a certain gas sample has a volume of 765 ml. a. What would be its new volume if the temperature and pressure were changed to 57°C and 792 Torr? Hint: Use Combined Gas Law. b. How many moles are present in that gas sample? Hint: Use Universal Gas Law.
