Answer:

So, in #100*g# of solution there are #3.5*g# of salt, and the balance water?

Explanation:

By definition...#"1 ppm"=(1*mg)/(1*L)#...most of the time we can ignore the density because the mass of the solute is miniscule...here we assume that the #96.5*g# of solvent water expresses a volume of #96.5*mL#...

And so we take the quotient....

#(3.5*gxx10^3*mg*g^-1)/(96.5*mLxx10^-3*L*mL^-1)=36,269*"ppm"#
