Which of the following solutions is the most concentrated? ?

20mg/L or 20 ug/uL? Thanks!

    20 μg/uL

    = (20 μg/uL) × (1 mg/1,000 μg) × (1,000,000 uL / 1 L)

    = 20,000 mg/L

    > 20 mg/L

    Hence, 20 μg/uL is more concentrated than 20 mg/L.

    m = 10^-3

    20 mg/L = 0.020 g/L

    20 ug/uL = 20 g/L

    So the second solution is more concentrated by a factor of 1000.

    20 ug/uL = 20 g/L, which is clearly much larger than 20 mg/L (=0.02g/L).
