Question

1000 gram aqueous solution of $CaC{O}_3$ contains 10 gram of carbonate. Concentration of solution is:

• A. 10 ppm
• B. 100 ppm
• C. 1000 ppm
• D. 10, 000 ppm

Answer 1

The correct option is D 10, 000 ppm

The concentration of solution (ppm) $=\frac{wt.ofsolute}{wt.ofsolvent}\times {10}^6=\frac{10}{{10}^3}\times {10}^6=10,000ppm$
