What is the volume of a cube of water that has a mass of 512g?
Water has a density of 1 gram/cm3.
Say for example you have an ice cube of which you need to find the volume..First find something that sinks in water..Next,dip it in water and find the volume of water it displaces..For this a Decanting Can might come in handy..Now tie the ice cube with a string of negligible mass and thickness to the mass that sank in water and lower it into water so that the ice cube is completely immersed in water..This…
Using the formula density = mass/volume. Take one ice cube, quickly weigh it, and then drop it into a measuring cylinder already filled with a quantity of water. record the change in volume, which is the volume of the ice cube. To calculate the density, calculate as follows: mass of ice cube / volume = density in grams/cm3
What has the greater density a cube of water measuring 1cmX1cmX1cm and having a mass of 1g or a block of plasting measuring 2cmX3cmX1cm with the mass of 4g?
Density = mass/volume For the cube of water having a mass of 1g: Volume of a cube of water measuring 1cm X 1cm X 1cm =1cm3. Density = 1g/1cm3 = 1g/cm3 For the block of "plasting" having a mass of 4g: Volume of the block of plasting measuring 2cm X 3cm X 1cm = 6cm3. Density = 4g/6cm3 = 0.7g/cm3 I will let you decide which has the greatest density.
Density = mass/volume The displaced volume of water is the volume of the 64-gram iron cube. Milliliters and cubic centimeters are equal, so we can give the volume of the iron cube as 8mL = 8cm3. Mass is given as 64g Density = 64g/8cm3 = 8g/cm3 However this would not be pure iron, as pure iron has a density of ~7.87g/cm3.
