The mass is given as m=45.0 lbs.
The given mass can be converted into grams as,
[tex]\begin{gathered} m=(45.0\text{ lbs)(}\frac{1\text{ kg}}{2.2\text{ lbs}})(\frac{1000\text{ g}}{1\text{ kg}}) \\ =20454.5\text{ g} \\ \approx20500\text{ g} \end{gathered}[/tex]Thus, the given mass in grams can be expressed as 20500 g.
