think about items you or your family bought over the last week. what kind of packaging was around those items? How did you dispose of it? Could you buy the same items without all packaging? pl help

its not that hard, i mean its a question that you kinda have to answer yourself. its basically asking you to write down the items that your family brought over the last week. just think of the things that your parents or family brought home. then you have to tell them what packaging was around the items, for example, plastic. and then etc.

Hope that helps you!

Solve for the molecules present in 1296 g of dinitrogen pentoxide (N2O5)

The molar mass of N2O5 is 108 g/mol. 

1296g of N2O5 has 1296 / 108 = 12 moles. 

1 mole contains 6.022 x 10^23 molecules. 

6.022 x 10^23 x 12 = 7.226 x 10^24 

Therefore, there are 7.226 septillion ( 7.226 x 10^24 ) molecules in 1296g of dinitrogen pentoxide.
