The density of lead is 11.3 g/mL. The water level in a graduated cylinder initially at 211 mL rises to 291 mL after a piece of lead is submerged. What is the mass in grams of the lead?

Explanation:

Volume of the lead peice = final V - initial V

                                      = 291- 211 = 80 ml

now from the density = mass/ Volume

                    11.3   =  mass/80

          mass= 904 g

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.
