#### Explanation:

The **density** of the metal is essentially the mass of exactly

#"22.5 g" color(blue)("/cm"^3) " " -> " " color(blue)("1 cm"^3)color(white)(.)"of osmium has a mass of 22.5 g"#

So, you know that your sample fo osmium has a volume of *conversion factor*

#43.2 color(red)(cancel(color(black)("cm"^3))) * "22.5 g"/(color(blue)(1)color(red)(cancel(color(blue)("cm"^3)))) = color(darkgreen)(ul(color(black)("972 g")))#

The answer is rounded to three **sig figs**.
