Density depends on 2 things, mass and volume. If you don't know the volume you cannot calculate the density.
The density would be 6 g/mL. To calculate density, divide the mass (30g) by the volume (5mL). Density = mass/volume = 30g / 5mL = 6 g/mL.
density= mass/volume 30g/7500cm3=.004g/cm3
Density = Mass/Volume Volume of cube=5cmx5cmx5cm=125cm3 So 30g/125cm3=0.24g/cm3
The density of the object is 3 g/ml. Density is calculated by dividing the mass of an object by its volume. In this case, 30g divided by 10ml equals 3 g/ml.
30g/cm3
The density of the mineral would be 2 g/ml (density = mass/volume).
density = mass/volume volume = mass/density mass = volume*density Here are some numbers from a recent chem experiment that prove this. 4.360g/mL = 30g/6.88mL 6.88mL = 30g/4.360g/mL 30g = 6.88mL*4.360g/mL
30g=15c cm=60c cm density
30g=15c cm=60c cm density

You don't need density to find mass. In a lot of question you need to find density with the given mass and volume. But to find density you would use a triple beam balance. To find volume you would either measure the length, width and height or you could fill a beaker up with water lets say 50g and then put the object in the beaker and lets say it raised up to 80g all you have to do is subtract 80g-50g=30g. To find density with volume and mass you divide mass------volume and get density.
The density of sodium at room temperature is 0.968g/cm3. Density = mass/volume. To find the volume of a substance from its density and mass, divide the mass by the density. V = M/D = 30g/0.968g/cm3 = 31cm3
