Solutions Part 2

Sea water, which can be considered as a 6 molar ( 6 M ) solution of NaCl , has a density of 2gmL−1. The concentration of dissolved oxygen ( O2 ) in sea water is 5.8 ppm . Then the concentration of dissolved oxygen (O2) in sea water, is x×10−4m. x= ____ . (Nearest integer) Given: Molar mass of NaCl is 58.5gmol−1 Molar mass of O2 is 32gmol−1
