Keeping the following points in mind we can calculate the number of atoms in a unit cell. * An atom at the corner is shared by eight unit cells. Hence an atom at the corner contributes 1/8 to the unit cell * An atom at the face is a shared by ..

The most common unit for mass is expressed in grams (g) or kilogram (kg) (1 kg = 10 3 g). In chemical measurement, IUPAC prescribes that the mass of a gas (m) be expressed in terms of the number of moles (n). The number of moles can be obtained from the mass of the gas using the relation..

The circle graph gives the measure of the central angle for each category. Calculate the percent of the Hispanics in the United States. => 55% or 25% or 50% or 60%..

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..

Units of Equilibrium Constant - In mathematical sense, equilibrium constant is not a constant. It is called constant because at a fixed temperature and pressure, the value of the equilibrium constant for a reaction is constant. The unit of equilibrium constant (K) of a reaction ..

Units of concentration (in aqueous solutions) is moles per litre Unit of time is seconds, minutes etc. For e.g., Consider a hypothetical reaction The rate of a reaction may be expressed in either of the following two ways: 1) The rate of disappearance or decrease i..

In quadrilateral ABCD, the diagonal BD measures 6 units. The lengths of the perpendiculars drawn to the diagonal BD are AY = 2 units and CX = 3 units. Calculate the area of the quadrilateral ABCD. => 15 square units or 16 square units or 1..

Relation Between Atomic Mass Unit and MeV (Mass Energy Relation) - The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u). 1 a.m.u is defined as 1/12 t h of the mass of an atom of 6 C 1 2 isotope. It can be shown that 1 a.m.u = 1.66..

In the figure, ABCD is a quadrilateral with diagonal AC. The diagonal divides the quadrilateral into two triangles, ABC and ADC. The ratio of the area of ΔABC to ΔADC is 2 : 3. If the area of quadrilateral ABCD = 10 square units, calculate the difference between the ..

Which of the following represents the graph of f ( x ) = 2 x 3 -3 x 2 - 5 x + 1 and its real zeros to the nearest half unit? [Use a graphing calculator.] => Figure 2; real zeros of f ( x ) are - 2.6, 0.2 and 0.8 or Figure 1; real zeros of f ( x ) are - 1.1, 0.2 and 2.4..
