The organic compound di‑n‑butyl phthalate, C 16 H 22 O 4 ( l ) , is sometimes used as a low‑density ( 1.046 g ⋅ mL − 1 ) manometer fluid. Compute the pressure in torr of a gas that supports a 463 mm column of di‑n‑butyl phthalate. The density of mercury is 13.53 g ⋅ mL − 1 .

If a plot weight (in g) vs. volume (in ml) for a metal gave the equation y= 13.41x and r^2=0.9981 what is the density of the metal?
