Use the equаtiоns belоw tо solve the following gаs lаw problem. P1V1T2 = P2V2T1 1 atm = 760 mm Hg = 760 torr A sample of gas collected at 21.0°C and 660 mm Hg, has a volume of 1.83 liters. What will the pressure of the gas be if the temperature is increased to 38.0°C and the volume is reduced to1.50 liters? To receive full credit: You must use the math equation editor in the tool bar to insert the final gas law equation (with numbers and units) that you used to solve the problem. Show your work (equation/and units) by using the equation editor() in the toolbar. If necessary, use the the three vertical dots to expand the toolbar. Within the equation editor, use to insert ratio. Be sure to include proper units and the final answer! Or, show your work on a separate sheet of paper and submit in the Unit 2 Exam pictures dropbox after completing the Exam.
