उत्तर
1000 g aqueous solution of CaCO3 contains 10 g of calcium carbonate. Concentration of the solution is 10000 ppm.
Explanation:
Mass of solution = 1000 g
Mass of CaCO3 (solute) = 10 g
Hardness or Concentration (ppm) = `"mass of solute"/"mass of solution" xx 10^6`
= `10/1000 xx 10^6`
= 10000 ppm
