the table shows the solubility of two substances in water at 20 °c.
solubility of substances
mass
(kg) solubility of sodium chloride
(g per 100 g of water) solubility of lead nitrate
(g per 100 g of water)
100 l k
200 36 54
part 1: what will be the values of l and k for 100 kg of each substance?
(this one's 35, i just need the second part. explain why.)
part 2: explain your answer for part 1.

Crinoids, also known as sea lilies, appear to be sea plants but are not plants at all. crinoids are an echinoderm species which uses anchoring structures called holdfasts to attach themselves to the sea floor. crinoids were most abundant in pennsylvania during the mississippian period, which ranged from 375 to 320 million years ago. fossils of the crinoids shows that during most of this time pennsylvania was that provided favorable conditions for crinoid growth. a) glacial terrain b) a dry and sandy plain c) mostly mountain ranges d) covered by warm, shallow seas
