Question #efc79

Answer 1

`"Molarity"~=5*mol*L^-1`

Explanation:

`"Molarity"` `=` `"Moles of solute"/"Volume of solution"`.

And thus............

`"Molarity"` `=` `((290.0*g)/(58.44*g*mol^-1))/(1*L)=4.96*mol*L^-1.`

This is impossibly salty sea water. You are out by an order of magnitude. This site reports a salinity of `35*g*L^-1`
