∙ 13y agoDensity=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/volume = 350/150 = 2.33 grams/cubic centimeter
density = mass divided by volume = 100/25 = 4 grammes per cubic centimetre.
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.
The density of the rock is 20 grams/cm3. You can calculate density by dividing the mass by the volume.
You need the mass and volume to calculate the density
To calculate density, you need to divide the mass of the rock by its volume. In this case, the density of the rock would be 12g divided by its volume in cm^3. Without knowing the volume in cm^3, it is not possible to determine the density of the rock.
The density of the rock is calculated by dividing its mass (56 grams) by its volume. If the volume is unknown, then the density cannot be determined. Density is the mass per unit volume of a substance, so both mass and volume need to be known to calculate it.
A rock with a volume of 4mL would have a greater mass than a rock with a volume of 1mL. Mass is directly proportional to volume, so as volume increases, mass also increases assuming the density of the rocks is constant.
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
To calculate the density of an irregular object like a rock, you can measure its mass using a scale and then determine its volume using the water displacement method. Once you have the mass and volume, you can divide the mass by the volume to obtain the density of the rock.
The density of the rock is calculated by dividing the mass by the volume. In this case, the density would be 29.6 g/cm³ (234 g / 7.9 cm³).
The density of the rock can be calculated by dividing the mass of the rock (127g) by the volume of water it displaces (32.1 mL). The density of the rock is 3.95 g/mL.
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
The rock may have a higher density due to its composition, such as being made of dense materials like metals or minerals. Density is mass per unit volume, so even though the rock is smaller and lighter overall, its mass is concentrated in a smaller volume, resulting in higher density. This higher density allows the rock to sink in water, which has a lower density.
