We’re being asked to calculate the concentration of NH3 in the solution, expressed as parts per million (ppm).
Let’s first define ppm.
• 1 ppm means 1 part of solute for every 106 parts of the solution
Can be written as:
A 2,400-gram sample of an aqueous solution contains 0.012 gram of NH3. What is the concentration of NH3 in the solution, expressed as parts per million?
A) 15 ppm
B) 50 ppm
C) 20 ppm
D) 5.0 ppm
