you need 100.00 ml of h20 and 5.00 ml of
liquid plant food to make a solution for your
plants. you forgot to bring a measuring cup
out to the greenhouse, but you do have a scale
and know that the density of h2o is 1.00
g/cm", the density of liquid plant food is 1.21
g/cm' and 1 cm° = 1 ml. how much of the
liquid plant food would you use?

If you chip a tooth, most likely you will go to the dentist to have the missing material filled in. currently the material used to fill in teeth is a polymer that is flexible when put in, yet is hardened to the strength of a tooth after irradiation with blue light at a wavelength of 461 nm. what is the energy in joules for a photon of light at this wavelength?
