11) A balloon weighing 144.85 g is filled with carbon dioxide and reweighed. The weight of the balloon plus gas is 153.77 g. The volume of the full balloon is 4.55 L. Calculate the density of carbon dioxide?

1.96 grams per liter

Explanation:To find density you have to divide mass by the volume d=m/v

Now you need to find the mass of the carbon dioxide by 153.77- 144.85= 8.92 grams

Finally all you do is 8.92/4.55= 1.96 grams per liter

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.
