Question

sea water contains 53 ppm of Na2CO3.Find mass of Na2CO3 present in a glass of water.

Answer 1

Answer:

Concentration in ppm =

mass of solute/mass of solution×10-6

mass of solute Na2Co3=X g

mass of solution =mass of soluteNa2co3× mass of water=Xg+100

53=X g/X g+100 ×10-6

CONCENTRATION in ppm=5.3×10-3
