The mass of a piece of metal is 1200 g. A measuring cylinder contains 150 cm3 of water. The piece of metal is put into the measuring cylinder. The water level rises to 250 cm3 and covers the metal.
What is the density of the metal?
3.0 g / cm3
4.8 g / cm3
8.0 g / cm3
12.0 g / cm3
A person measures the length, width, height and mass of a metal block with rectangular sides.
Which of these measurements must be used in order to calculate the density of the metal?
mass only
height and mass only
length, width and height only
length, width, height and mass
A liquid has a volume of 100 cm3 and a mass of 85 g.
The density of water is 1.0 g / cm3
.
How does the density of the liquid compare with the density of water?
Its density is higher than that of water.
Its density is lower than that of water.
Its density is the same as that of water.
It is impossible to say with only this data.
A measuring cylinder has a mass of 120 g when empty.
When it contains 50 cm3 of a liquid, the total mass of the measuring cylinder and the liquid is
160 g.
What is the density of the liquid?
5040 cm3g
4050 cm3g
50120 cm3g
50160 cm3g

balance, measuring cylinder and ruler
balance and thermometer
measuring cylinder and ruler
measuring cylinder, ruler and thermometer
A student wishes to find the volume of a piece of wood of irregular shape. Her experiment requires
the use of a small brass object of mass 200 g.
(a) Calculate the volume of the brass object. The density of brass is 8.4 g / cm3.
volume = (a) [2]
A student has 500 identical, rectangular sheets of paper. The mass of 1.0 m2 of the paper is 0.080 kg.
(a) Using a metre rule, she measures the length of one sheet of paper and its width. The length is 0.300 m and the width is 0.210 m.
(i) Calculate the mass of one sheet of paper.
mass = (a) [1]

The density of aluminium is 2.70 g / cm3. The thickness of a rectangular sheet of aluminium foil varies, but is much less than 1 mm.
A student wishes to find the average thickness. She obtains the following measurements.
mass of sheet = 60.7 g
length of sheet = 50.0 cm
width of sheet = 30.0 cm
Calculate the student’s values for
(i) the volume of the sheet,
volume = (a) [2]
