What is the density of silicon dioxide?
Silicon dioxide has a density of 2.63 g/cm3.
How many atoms are there in 1 cm3 of iron?
The density of iron, Fe, at room temperature is 7.874 g/cm3. So 1cm3 of iron has a mass of 7.874g. 1 mole iron = 55.845g Fe = 6.022 x 1023 atoms Fe. 7.874g Fe x 6.022 x 1023 atoms Fe/55.845g Fe = 8.491 x 1022 atoms Fe
What is the density of mass 1800 and volume 200 cm3 and the material is copper?
density= mass/volume =1800g/200cm3 divide density= 9 g/cm3
How many kg equal cm3?
Of what ??
Which pair of quantities determines the density of a material?
Density = Mass/volume Therefore the quantities are mass (g) and volume (cm3)
How many atoms1 cm3 for silicon?
Number of atoms in a unit cell:4 atomscompletely inside cellEach of the 8 atoms on corners are shared among cells count as 1 atom inside cellEach of the 6 atoms on the faces are shared among 2cells  count as 3 atomsinside cellTotal number inside the cell = 4 + 1 + 3 = 8Cell volume:(.543 nm)3 = 1.6 x 10-22 cm3Density of silicon atoms= (8 atoms) / (cell volume) = 5 x 1022 atoms/cm3
What is the mass of a 350 cm3 sample of pure silicon with a density of?
2g/cm3
What is the density of silicon dioxide?
Silicon dioxide has a density of 2.63 g/cm3.
How many ounces in 100 cm3?
Depends on the material
Compute the density of an 820g sample of pure silicon occupying a 350 cm3 container?
2.34285714g/cm3
What is the density of solid material with 24g of mass and 4.8 cm3 of volumes?
The solid material has a density of 5 g/cm3
How many atoms are there in 1 cm3 of iron?
The density of iron, Fe, at room temperature is 7.874 g/cm3. So 1cm3 of iron has a mass of 7.874g. 1 mole iron = 55.845g Fe = 6.022 x 1023 atoms Fe. 7.874g Fe x 6.022 x 1023 atoms Fe/55.845g Fe = 8.491 x 1022 atoms Fe
How many atoms are there in solid iron?
Impossible to answer without knowing a mass or a volume. But I can tell you that there are 6.022x10^23 iron atoms (one mole) for every 55.845 grams of iron. That translates to: 1.078x10^22 iron atoms per gram or given that the density of iron is 7.87 g/cm3 at 25 degrees Celsius... 8.487x10^22 iron atoms per cm3.
Will 0.92gmL sink in water?
If you think to a material with the density of 0,92 g/cm3, this material float on water.
How many cm3 in 1m3?
10 000 cm3
What is the mass of 1 cm3 of a mateial?
The mass of a given volume of a material is dependent on the material's density, and thus its molecular weight. So, this will differ for every type of material, and there is therefore no absolute weight for 1ml (cm3) of a material. The only universal measure of mass that holds for all materials is the 'mole.' A mole is defined as 6.022 x 1023 atoms of a given substance. Multiplying the atomic mass of a given element or molecular weight of a given compound by this number yields the mass of one mole of the element, in grams. If the density of a given substance is known, the mass per cm3 can then be calculated. Frequently in chemistry, the density of a substance is compared to the density of water (H2O), which is 1g/ml.
What is the density of a material that has a mass of 23.9 g and a volume of 27.5 mL?
the book density is:7g/cm3 or 0.007kg/cm3.
