Question 2

Tricia puts 66 g of dry ice (solid CO2) into a 2.0-L container and seals the top. The dry ice turns to gas at room temperature (20C). Find the pressure increase in the 2.0-L container. (One mole of CO2 has a mass of 44 g and R = 0.0821 Latm/molK. Ignore the initial volume of the dry ice.)
 a. 6.0 atm
  c. 18 atm
  b. 12 atm
  d. 2.0 atm
