Well, we need to add a mass of #1.48*g# with respect to the salt SODIUM SULFATE to a one litre volume of water...

Explanation:

And we interrogate the molar quantities of sulfate dianion...

#"Moles of sulfate"=(1.00*g)/(96.06*g*mol^-1)=0.0104*mol#.

And with respect to the salt sodium sulfate we take a mass of....

#0.0104*molxx142.04*g*mol^-1=1.48*g#...and this added to a one litre volume of water....

And note that #"1 ppm"-=1*mg*L^-1#...hence #"ppm"# given that there are #1000xx1000=10^6*mg# in one litre of water; considerations of altered density are unimportant at these concentrations....
