Iron pyrite (FeS2) has a density of 4.8 to 5.0 grams per cm3. A piece of volume 40 cm3 would, therefore have a mass of volume*density = 192 to 200 grams.
The density of pyrite is about 5 g/cm³. To find the mass of the pyrite, you can use the formula: mass = density x volume. Therefore, in this case, the mass of the pyrite would be 50 grams.
Density = Mass/Volume = 62.8/40 = 1.57 g/cm3.
density = mass/volume = 2g/40cm3 = 0.05g/cm3
Density = Mass/Volume = 57.2g/11 cm3 = 5.2 gcm-3
The density of the cork can be calculated by dividing its mass (10g) by its volume (40cm³). Thus, the density of the cork is 0.25 g/cm³.
Gold has a higher density than pyrite, which means it contains more mass in the same volume. This higher density is due to the atomic structure and composition of gold, which makes it heavier compared to pyrite even though they may appear to be the same size.
-- Get a pure piece of it. The size of the piece doesn't matter. -- Measure the mass of the piece. -- Measure the volume of the piece. -- The density of the substance is mass of the piece/volume of the piece.
The nugget of gold has a volume of 2.6 cm3, and the nugget of pyrite has a volume of 10 cm3.
Since the density of gold is higher than that of iron pyrite, the gold nugget will have a smaller volume than the iron pyrite nugget. This is because for two materials with the same mass, the denser one will occupy less space.
If the volumes of the samples of pyrite and gold are equal, you cannot directly determine the number of samples without knowing the specific mass or density of each material. Pyrite has a lower density (about 5 g/cm³) compared to gold (about 19.3 g/cm³), meaning that for the same volume, a sample of gold would weigh significantly more than a sample of pyrite. Therefore, while the volumes may be equal, the mass of gold will be greater than that of pyrite.
Pyrite has a density of 4.8-5g/cm3 mass = density x volume = (4.8-5)g/cm3 x 10 cm3 = 48 to 50 grams.
Volume = mass/volume = 500g/10cm3 = 50g/cm3
