Calculate the number of pounds of co2 released into the atmosphere when a 17.0-gallon tank of gasoline is burned in an automobile engine. assume that gasoline is primarily octane, c8h18, and that the density of gasoline is 0.692 g·ml–1 (this assumption ignores additives). also assume complete combustion.

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
