The rock's density is 3 g/cm3
Density=mass/volume.......but make sure units match up.
Density = mass/volume Density = 22.4g/8cm3 = 2.8g/cm3 or 3g/cm3 if significant figures are considered.
Density = Mass/Volume = 50g/12.5mL = 4 g per mL
density = mass divided by volume = 100/25 = 4 grammes per cubic centimetre.
density = mass/volume = 350/150 = 2.33 grams/cubic centimeter
Mass is measured by density multiplied by volume. In order to figure out a mass of a rock, one must know its density and its volume measurements.
You need the mass and volume to calculate the density
The mass of a rock is just how much it weighs. Density on the other hand can be found by finding the volume or size of the rock (most easily done in small objects by placing the rock into a beaker or graduated cylinder with markings to see how much water the rock displaces. Completely submerge the rock antd the increase in volume in the water is the volume of the rock). Once you know how much volume there is and how much mass there is (mass is how much it weighs) divide the mass by the volume which gives you the density. Density=Mass÷Volume
density = mass / volume d = 234g / 7.9cm = 29.6 g/cm
The answer depnds on the density of each rock. If they are different denities thenthere is a chance that the 1mL rock may have more mass. If they have the same density then the 4mL rock will have more mass
You have answered this question for yourself. The Density is 0.94 g/mL However, do you mean , 'what is the rocks volume?' Remember the eq'n density = mass./ volume. Algebraically rearranged volume = mass / density Hence volume = 20g/ 0.94 g/mL volume = 2.276 mL
Density=mass/volume.......but make sure units match up.
Determine its volume by how much water it displaces, then divide mass by volume
Density = mass/volume Density = 22.4g/8cm3 = 2.8g/cm3 or 3g/cm3 if significant figures are considered.
The rock has a density of 10 g/cm3
Density = Mass/Volume = 25g/5ml = 5 grams per mL.
Density = Mass/Volume = 50g/12.5mL = 4 g per mL
