Question

This is for my physical science class.Two-Step Conversion:How many grams is 45.0 lbs? (Remember your answer need to have the correct amount of significant figures and the correct units written).(1 Kg = 2.2 lbs)

Answer 1

The mass is given as m=45.0 lbs.

The given mass can be converted into grams as,

`\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}`

Thus, the given mass in grams can be expressed as 20500 g.
