Detailed Solution

Total mass in 10 micrograms,

$M = = 10 \times 10^{- 6} grams$

Here, the volume is 0.1 liter.

Now we know that,

$Concentration in ppm = \frac{Mass}{Volume} \times 10^{6}$

Put the given values,

$Concentration in ppm = \frac{10 \times 10^{- 6}}{0.1} \times 10^{6} Concentration in ppm = 100$
