45/15= 3 Where density is equal to mass over volume
Density = Mass / Volume Rearranging this gives: Volume = Mass / Density Mass = Density × Volume
volume = mass/density and density = mass/volume
density=mass/volume volume=mass/density
You have to know two out of three ... mass, volume, density ... then you can find the missing one. If density is missing . . . Density = (mass)/(volume) If mass is missing . . . Mass = (density) x (volume) If volume is missing . . . Volume = (mass)/(density)
You need some aluminum, a scale to determine the mass, and a measuring cup halfway filled with water to determine the volume of the piece of aluminum by substracting the volume after and before you drop the piece of aluminum in the water. Then you can calculate the density of the aluminum = mass / volume.
The density of aluminum is approximately 2.7 g/cm^3. To calculate the density of an aluminum cylinder, you would need to know its mass and volume, and then divide the mass by the volume to get the density.
If you divide the mass by the volume, for any object, you get its density.
To find the volume of 8.1 g of aluminum, you can rearrange the density formula (Density = Mass/Volume) to Volume = Mass/Density. So for 8.1 g of aluminum and a density of 2.7 g/ml, the volume would be 8.1 g / 2.7 g/ml = 3 ml.
Lead has a higher density compared to aluminum. So, to find the mass of lead that occupies the same volume as 100g of aluminum, you would first calculate the volume of the aluminum using its density. Then, you would find the mass of lead that occupies the same volume by using the density of lead.
The mass and volume of aluminum are related by density: mass = volume x density and density depends upon temperature and pressure. Aluminum has a density of 2.70 grams per cubic centimeter in its solid state. In its liquid state, Aluminum has a density of 2.375 grams per cubic centimeter.
Density equals mass over volume (mass divided by volume), so you simply divide 34.6 g by 12.8 mL (you don't need to convert any units because the density unit is g/mL).
Since the density of aluminum is 2.7 g cm-3, a sample with a mass of 5.4 would have a volume of 2 cm3.
To find the volume of 54 grams of aluminum with a density of 2.7 g/cm3, divide the mass by the density: 54 grams / 2.7 g/cm3 = 20 cm3. Therefore, the volume of 54 grams of aluminum is 20 cubic centimeters.
Calculate the volume of 66.7 g of cobalt using its density: Volume = Mass / Density = 66.7 g / 8.90 g/cm³ = 7.48 cm³. Use the volume to find the mass of aluminum it would occupy: Mass = Volume x Density = 7.48 cm³ x 2.71 g/cm³ ≈ 20.3 g of aluminum.
To calculate the weight of aluminum, you need to know the volume of the aluminum object (in cubic inches or cubic centimeters) and the density of aluminum (2.7 g/cm3 or 0.098 lb/in3). Multiply the volume by the density to find the weight of aluminum in grams or pounds.
The 10 cm3 of aluminum would have a higher density compared to the 5 cm3 of aluminum. Density is a physical property defined as mass per unit volume, so in this case, the larger volume (10 cm3) would contain more mass, resulting in a higher density compared to the smaller volume (5 cm3).
