Question

question 4 (1 point)
0.00028 g = ________ mg

blank 1: |

Explanation:

Step1: Recall unit conversion factor

We know that \(1\ \text{g} = 1000\ \text{mg}\), which can be written as the conversion factor \(\frac{1000\ \text{mg}}{1\ \text{g}}\).

Step2: Multiply by conversion factor

To convert \(0.00028\ \text{g}\) to \(\text{mg}\), we multiply \(0.00028\ \text{g}\) by the conversion factor:
\[
0.00028\ \text{g} \times \frac{1000\ \text{mg}}{1\ \text{g}}
\]
The \(\text{g}\) units cancel out, and we calculate \(0.00028\times1000 = 0.28\).

Answer:

\(0.28\)
