# Calculating Volume, Pressure & Density

1. A sample of CO2 gas at 22°C and 7.71 atm has a volume of 6.0 L. If the pressure decreases to 5.42 atm, what is the volume? (Round your answer to one decimal place)

2. 120 mL of ethyl alcohol, C2H5OH, is poured into a soft drink bottle at room temperature. The ethyl alcohol weighs 32.4 g and the bottle is heated to 100°C. What is the pressure after heating? (Round your answer to the nearest whole number)

3. Calculate the density, in g/L, of SO2 at 75°C and 1.33 bar. (Round your answer to two decimal places)
