Answer:
0.84ppm
Explanation:
Mass of solute = 3.8 x 10⁻⁴g
Mass of solution = 450g
Unknown is the concentration in ppm; parts per million
The parts per million is one of the units of representing small concentration of solutes in a solution.
Solutes are the substances dissolving in another to give solution.
Here the concentration is expressed in a million units.
Concentration in ppm = [tex]\frac{mass of solute}{mass of solution}[/tex] x 10⁶
= [tex]\frac{3.8 x 10^{-4} }{450}[/tex] x 10⁶
= 0.84ppm
