A solution is prepared by mixing 30,0g sucrose with 30,0g. what is a concentration expressed in ppm?
I assume you mean 30 g H2O.
ppm = mg/1000 g if you want w/w (mass/mass ppm)
30g/30g = 1 g/1 g. Convert to mg/1000 g.
ppm = mg/1000 g if you want w/w (mass/mass ppm)
30g/30g = 1 g/1 g. Convert to mg/1000 g.
