PLZZZ HELP You are designing artificial plasma. The plasma must have a salinity between 30 ppt and 40 ppt. Which of the sample solutions from the table above fit this requirement?

i think multipling 30 to the 40

30 × 40 = 1200ppt

so what is the problem with your lab report and whats the subject of the lab report? i will you

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.

if it's not useful, feel free to report for mistake in answer.
