Density Mass Volume : 

Density Mass Volume

Density : 

Density Density compares the mass of an object with its volume D = mass = g or g volume mL cm3 Note: 1 mL = 1 cm3

Density : 

Density Density is a measure of the mass of something in relation to its volume, measured by a unit of Mass divided by a unit of Volume. It is the ratio of its mass to its volume

Density : 

Density Density = Mass/Volume Units – g/cm3 Or g/mL (millilitre)

Density Mass Volume : 

Density Mass Volume Density = Mass / Volume Mass = Density x Volume Volume = Mass / Density D V M

Density Mass Volume : 

Density Mass Volume Osmium is a very dense metal. What is its density in g/cm3 if 50.00 g of the metal occupies a volume of 2.22cm3? 1) 2.25 g/cm3 2) 22.5 g/cm3 3) 111 g/cm3

Solution : 

Solution 2) Placing the mass and volume of the osmium metal into the density setup, we obtain D = mass = 50.00 g = volume 2.22 cm3 = 22.522522 g/cm3 = 22.5 g/cm3

Volume Displacement : 

Volume Displacement A solid displaces a matching volume of water when the solid is placed in water. 33 mL 25 mL

Volume : 

Volume What is the density (g/cm3) of 48 g of a metal if the metal raises the level of water in a graduated cylinder from 25 mL to 33 mL? 1) 0.2 g/ cm3 2) 6 g/cm3 3) 252 g/cm3 33 mL 25 mL

Solution : 

Solution 2) 6 g/cm3 Volume (mL) of water displaced = 33 mL - 25 mL = 8 mL Volume of metal (cm3) = 8 cm3 Density of metal = mass = 48 g = 6 g/cm3 volume 8 cm3

Density : 

Density Which diagram represents the liquid layers in the cylinder? (K) Karo syrup (1.4 g/mL), (V) vegetable oil (0.91 g/mL,) (W) water (1.0 g/mL) 1) 2) 3) K K W W W V V V K

Solution : 

Solution (K) Karo syrup (1.4 g/mL), (V) vegetable oil (0.91 g/mL,) (W) water (1.0 g/mL) 1) K W V

Mass : 

Mass The density of octane, a component of petrol, is 0.702 g/mL. What is the mass, in kg, of 875 mL of octane? 1) 0.614 kg 2) 614 kg 3) 1.25 kg

Solution : 

Solution One mL weighs 0.702 grams 874 mL weighs 874 times as much as 1 mL So it weighs 874 times 0.702 grams 874 x 0.702 = 613.548 g = 614 g when rounded Or: M = D x V = 874 x 0.702

Volume : 

Volume If blood has a density of 1.05 g/mL, how many litres of blood are donated if 575 g of blood are given? 1) 0.548 L 2) 1.25 L 3) 1.83 L

Solution : 

Solution Blood has a density of 1.05 g/mL To get 575 g of blood, we would need 575/1.05 times as much blood as is in 1 mL = 547.62 times as much = 547.62 mL, or 0.548 L when rounded. Or: V = M/D = 575/1.05

Density : 

Density You have 3 metal samples. Which one will displace the greatest volume of water? 1 2 3 Discuss your choice with another student. 25 g Al 2.70 g/mL 45 g of gold 19.3 g/mL 75 g of Lead 11.3 g/mL

Solution : 

Solution D = M/V, so V = M/D = 25/2.7 = 9.26 25 g Al 2.70 g/mL
