So there are two questions:
1.How many grams of NaCl are gained with the vaporization of sea water where wNaCl=2.7%?
2.How much dm3 are gained in normal conditions by the cooperation of 10 g sodium with water H2O.
Also sorry if there was bad grammar, I translated it myself.
I have tried using the w(BA) method I was taught at school but it didn't seem to work. Also I'll probably not understand your help (I live in an undeveloped country where we dont learn anything) so I'd really appreciate it if you folks could solve it for me, thanks!
