Seawater has a salinity of 3.5%, meaning that if you boil away a kilogram of seawater, when you're finished you'll have 35 g of solids (mostly NaCI) left in the pot. When dissolved, sodium chloride dissociates into separate Na+ and CI-ions.
Calculate the osmotic pressure difference between seawater and fresh water. Assume for simplicity that all the dissolved salts in seawater are N aCl.
Chromium(III) oxide reacts with hydrogen sulfide (H2S) gas to form chromium(III) sulfide and water:Â
Cr2O3(s) + 3H2S(g)→Cr2S3(s) + 3H2O(l)
To produce 681 g ofCr2S3Â
(a) how many moles ofCr2O3are required?
(b) how many grams ofCr2O3are required?
