Question

d) 2 μg = ＿ kg

Explanation:

Step1: Recall the conversion factor

We know that $1\ \text{kg} = 10^{9}\ \mu\text{g}$, so $1\ \mu\text{g}=10^{- 9}\ \text{kg}$.

Step2: Convert 2 μg to kg

Multiply 2 by the conversion factor. If $1\ \mu\text{g}=10^{-9}\ \text{kg}$, then $2\ \mu\text{g}=2\times10^{-9}\ \text{kg}=0.000000002\ \text{kg}$.

Answer:

$0.000000002$
