From density triangle D= m/v V V = m/D m = D x Volume unit can be mL or cm3 1) A block of aluminum occupies a volume of 15.0 mL and weighs 40.5 g. What is its density? 2) Mercury metal is poured into a graduated cylinder that holds exactly 22.5 mL. The mercury used to fill the cylinder weighs 306.0 g. From this information, calculate the density of mercury. 3) What is the weight of the ethyl alcohol that exactly fills a 200.0 mL container? The density of ethyl alcohol is 0.789 g/mL. 4) A rectangular block of copper metal weighs 1896 g. The dimensions of the block are 8.4 cm by 5.5 cm by 4.6 cm. From this data, what is the density of copper?

5) A flask that weighs 345.8 g is filled with 225 mL of carbon tetrachloride.
The weight of the flask and carbon tetrachloride is found to be 703.55 g.
From this information, calculate the density of carbon tetrachloride.
(hint: find the mass of carbon tetrachloride by subtracting mask of flask
from that of flask + carbon tetrachloride)

6) Calculate the density of sulfuric acid if 35.4 mL of the acid weighs 65.14
g.
7) Find the mass of 250.0 mL of benzene. The density of benzene is 0.8765
g/mL.
8) A block of lead has dimensions of 4.50 cm by 5.20 cm by 6.00 cm. The
block weighs 1587 g. From this information, calculate the density of lead.
9) 28.5 g of iron shot is added to a graduated cylinder containing 45.50 mL of
water. The water level rises to the 49.10 mL mark, from this information,
calculate the density of iron. (hint: calculate the volume of the iron by the
volume change of water due to displaced by iron)
