3. ### An empty vile weighs 31.45g. If the vile weighs 119.56g when filled with liquid mercury (d=13.53g/cm cubed)?

mass of Hg = (119.56 g - 31.45 g) = 81.11 g volume of mercury.... 88.11 g Hg x (1 cm³ /13.53 g) = 6.512 cm³.... 4 sig figs.

9. ### Density of a piece of wood is 0638g/mL. Dimensions of a wood block are 40cm by 50 cm by 25 cm.what is the mass

Find the volume....L x W x H, then use the formula M=D xV....your answer will be in grams, the mL and cm3 will cancel one-another out, since cm3 and ml are equal units of volume.
