Answer
$ 170\text{ lb}$
Work Step by Step
Converting 4 liters to cubic centimeters gives :
$4\text{ L }\times\frac{1000\text{ cm}^{3}}{1\text{ L}} = 4000 \text{ cm}^{3}$
So, the volume of the bucket is $4000 \text{ cm}^{3}$.
Use the density of gold to determine the mass in grams:
$\text{Mass of gold} = 19.3 \frac{\text{g}}{\text{cm}^3} \times 4000 \text { cm}^{3} = 77,200\text{ g}$
Converting the mass from grams to pounds gives :
$77,200\text{ g}\times\frac{1\text{ lb}}{454\text{ g}}\approx 170\text{ lb}$
