calculating the volume from density

.3 g cm - 3 (19300 kg m - 3 ). If the mass and volume of a substance can be measured, its density can be calculated using the formula Let us take a piece of wood which has a volume of 1000 cm 3 and a mass of 600 g. Then its density = 0.6 g cm - 3 (6..

Density - 0.5 kg of cotton occupies more space than 0.5 kg of iron. The particles of iron are closely packed while that of cotton are loosely packed. The amount of iron packed in a unit volume is more. This explains as to why iron is heavier than the same volume of cot..

The densities of alkali metals are low as compared to other metals, with Li, Na and K being even lighter than water (K is lighter than Na). While alkali metals do have close packing of metal atoms in their lattice the large size of their atoms cause them to have low densities. ..

Find the weight (W 1 gf) of a solid in air using a hydrostatic balance as shown in figure belo..

Let, The mass of the organic compound taken be = W g Volume of air displaced = V 1 mL Atmospheric pressure = P mm of Hg Room temperature, T 1 = t o C = (t + 273)K Aqueous tension at t o C = p mm of Hg Pressure of the dry air, P 1 = (P-p) mm Hg ..

Let, The mass of the acid dissolved be = W g Volume of alkali used for complete neutralization of acid solution = V 1 mL Normality of the alkali solution = N 1 Then, we can write, V 1 mL of alkali solution having normality N 1 = Wg acid From the definition, 1000 mL of 1N alkali so..

Since gases have large intermolecular spaces, they have very large volumes when compared to their mass. Thus they have low densities. If one ml of water at 39.2 o F is converted into steam at 212 o F and 1 atmosphere pressure, it will occupy a volume of 1700 m..

Water is the most common liquid. Density of water at 4 o C is 1 g cm - 3 (1000 kg m - 3 ). Example : 28 kg of fuel completely fills a 40 liter petrol tank of a vehicle. What is the density of the fuel? (1 liter = 10 - 3 m 3 ) Suggested Answer : Mass of fuel = 2..

The edge length of a cubic crystal can be obtained from X-ray studies and knowing the crystal structure possessed by it so that the number of particles per unit cell are known, the density of the crystal can be calculated..
