An iron engine block had a mad of 175kg. Determine the mad an airplane designer save if the engine block was made of aluminum instead of iron?
Density = mass / volume
Iron density = 7.8 (10^3kg/m^3 or g/mL)
Aluminium density = 2.7 (10^3kg/m^3 or g/mL)

1) What mass (in kg) of iron must be placed on top of the wood block so that the wood block is just barely submerged (the top of the block of wood is level with the surface of the water and the iron on top is in the air). The volume of the wood block is 0.00782 m^3. The density of the wood is 620 kg/m3 and the density of the water is 1000 kg/m3. 2) Most cars have hydraulic...

Part C Iron has a density of 7.86 g/cm (1 cm = 1 mL). Calculate the volume (in dL) of a piece of iron having a mass of 4.25 kg . Note that the density is provided in different units of volume and mass than the desired units of volume (dL) and the given units of mass (kg). You will need to express the density in kg/dL (1 cm = 1 mL) before calculating the volume for the piece of...

A 15.00 g metal sphere was found to have a diameter of 1.85 cm. The volume of a sphere is V = (4/3)pir^3. Calculate the density of the sphere and assuming that the sphere is made out of one of the elements, aluminum, chromium, iron, lead, titanium or zinc, determine its composition. A 5581 gram irregular object made out of one of the metals in #6 raises the water level in a graduated cylinder from the 17.6 mL level to...

When a block of volume 1.27 times 10^-3 m^3 is hung from a spring scale as shown in Figure A. the scale reads 9.0 N. When the same block is then placed in an unknown liquid it floats with 2/3 of its volume submerged as suggested in Figure B. The density of water is 1.00 times 10^3 kg/m^3. Determine the mass of the block. Determine the density of the unknown liquid.
