Assuming that sea water is a 3.50 wt% aqueous solution of NaCl. What is the molality of sea water?

Answer»

Assuming 100 g of sea water,it contains 3.5 g of Nacl.No of moles of Nacl=3.5/58.4=0.06 molesso for 100 gm of sea water,no of moles is 0.06so molality=0.06/100=0.0006let me know if this right and it is not,I'll revise it for you.
