Answer:
[tex]2.17*10^{12}[/tex] nanograms.
Explanation:
1 pound is approximately 0.454kg. (Divide by 2.205)
Hence, 4.8 pounds will be [tex]4.8/2.205=2.177[/tex]kg
1kg = [tex]1*10^{3}[/tex]grams
1 nanogram = [tex]1*10^{-9}[/tex]
[tex]3-(-9)=12[/tex]
Hence, 2.177kg is [tex]2.17*10^{12}[/tex]
Therefore, 4.8 pounds is [tex]2.17*10^{12}[/tex] nanograms.
