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
Nuclear reaction involves two reacting particles a heavy target nucleus and a light bombarding particle and produces two new particles a heavier product nucleus and a lighter ejected particle.
A consumer is like someone who eats out at a restaurant and a producer is like the chef making the food. Also a producer could be a actor and the consumer could be someone watching a movie.
The mass of carbon needed is 56g to get it to stop
to be honest I'm trying to give an educated guess hope I've helped
