how do you calculate average atomic mass

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..

Let, The mass of the organic compound taken be = W g Volume of nitrogen collected = V 1 g Atmospheric pressure = P mm Hg Temperature at which gas is collected = T 1 K Therefore, Pressure of the N 2 gas, P 1 = (P - p) mm of Hg..

Example: 29 - Calculate the volume of carbon dioxide formed at STP in 'ml' by the complete thermal decomposition of 3.125 g of pure calcium carbonate (Relative atomic mass of Ca=40, C=12, O=..

masses are not expressed as whole numbers because natural elements are mixtures of two or more isotopes. The atomic weight of chlorine is 35.43 amu. Chlorine exists as two isotopes in the ratio. Therefore average atomic masses are not whole numbers...

. Lyman series from n = 2, 3, 4, 5to n = 1 Balmer series from n = 3, 4, 5, 6to n = 2 Paschen series from n = 4, 5, 6, 7to n = 3 Brackett series from n = 5, 6, 7, 8to n = 4 Pfund series from n = 6, 7, 8, 9to n = 5. The energy of the electron in a particular orbit of hydrogen atom could be ..

Calculations Based on Chemical Equations - In a chemical reaction there is a rearrangement of particles. This rearrangement of particles, results in drastic changes in the properties of the substances. For e.g., sodium and chlorine are very reactive elements. When they combine, an electro..

The unit in which atomic and nuclear masses are measured is called atomic mass unit (a.m.u..

The quantity of an element whose mass in grams is numerically equal to its atomic mass. In simple terms, atomic mass of an element expressed in grams is the gram atomic mass or gram atom. For example, the atomic..

The nuclei of atoms are made up of protons and neutrons. These two components of the nucleus are referred to as nucleons. The electrons occupy the space outside the nucleus. Since an atom is electrically neutral, the number of protons in the nucleus is exactly equal to the numb..
