Answer: Triglyceride or Fat
Answer : The concentration of solution in ppm is, 500 ppm
Solution : Given,
Mass of solute (glucose) = 0.125 g
Mas of solution = 250 g
Parts per million (ppm) : It is defined as the mass of a solute present in one million
parts by the mass of the solution.
Formula used :

Now put all the given values in this formula, we get

Hence, the concentration of solution in ppm is, 500 ppm
