Density is defined as mass per unit volume.
the mass of 1 mL of CO₂ is - 0.0019 g
3.5 L = 3500 mL
then the mass of 3500 mL of CO₂ is - 0.0019 g/mL x 3500 mL = 6.65 g
mass of 3.5 L of CO₂ is 6.65 g
Endeavour is the youngest shuttle in NASA's orbiter fleet, and was built as a replacement for Challenger. The shuttle flew 25 missions over the course of its spaceflying career, logging a total of 122,883,151 miles (197,761,261 km) on its odometer. Endeavour launched on its maiden flight, STS-49, on May 7, 1992.
