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.
27.3 g is the mass of an aluminum sample with a volume of 10.0 cm3.
2g/cm3
The idea is to divide the mass by the volume.
This density is 0,8 g/cm3.
volume =mass/ density volume = 55.932/8.92 = 6.27 cm3
The density of aluminum is 2.70 g/cm3. To find the density of 100 cm3 of aluminum with a mass of 250g, divide the mass by the volume: 250g / 100 cm3 = 2.50 g/cm3. The density of the aluminum sample is 2.50 g/cm3.
27.3 g is the mass of an aluminum sample with a volume of 10.0 cm3.
In order to determine the mass of the water sample, you would need to know the density of water. The density of water is approximately 1 g/cm3. Therefore, the mass of a 20 cm3 sample of water would be 20 grams (20 cm3 * 1 g/cm3 = 20 grams).
The nugget of gold has a volume of 2.6 cm3, and the nugget of pyrite has a volume of 10 cm3.
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 or fool's gold is 5.01g/cm3
2g/cm3
The density of the ore sample is 1.97 g/cm3. This value is calculated by dividing the mass of the ore (57 g) by its volume (29 cm3).
To determine whether the nugget is real gold or fool's gold, you can calculate its density. The density of gold is 19.32 g/cm3, while the density of fool's gold (iron pyrite) is about 5 g/cm3. Based on the displacement of water and the mass provided, calculate the density of the nugget using the formula: density = mass/volume. Compare the calculated density to the known densities of gold and fool's gold to identify the material.
density = mass/volume = 250g/45cm3 = 5.6g/cm3 (rounded to 2 sig figs)
The mass of the nickel sample is 39.2 g (9.8 g/cm3 * 4 cm3), and the mass of the lead sample is 45.2 g (11.3 g/cm3 * 4 cm3).
Start by writing the formula that you probably know for density D=m/V Now plug in the data that you have: 2.336 g/cm3 = m/350 cm3 so, m = 350 x 2.336 = 817.6 g
