The correct answer would be 0.034 g/L.
<h3>Unit conversion</h3>
What we are trying to do here is to convert from milligram to gram and from deciliter to liter.
First, let's do the milligram to gram conversion.
1 mg = 0.001 g
Therefore,
3.4 mg = 3.4 x 0.001 = 0.0034 g
In order to convert from deciliter to liter.
1 deciliter = 0.1 L
Thus, 3.4 mg/dL = 0.0034g/0.1 L = 0.034 g/L
