Molar Mass: Typically, the molar mass represents the mass corresponding to the one mole of a chemical solution or mixture. It is usually computed by taking the ratio of mass and mole of a chemical mixture or element. We generally use gram per mole in chemistry to show the molar mass. Ans...
1 A silicon chip used in an IC of microcomputer has a mass of 5.68 mg.How many silicon (Si) atoms are present in the chip?2 Calcium carbonate (CaCO3),also called calcite,is the principal mineral found in limestone,marble,chalk,and pearls.(a) Calculate the molar mass of calcium ...
A compound is found to have a molecular mass of 90 atomic mass units and the simplest formula of C2H5O. What is the molecular formula of the substance? The percent composition by mass of a compound is 76.0% C, 12.8% H, and 11.2% O. The molar mass of...

For a given element, the mass (in grams) of one mole is given by its mass number on the periodic table; the "molar mass" of a molecule is the sum of the molar masses of the elements in the molecule in the correct ratios. It is simple to determine the molar mass of elements and ...
Once the cognate (recognition) sequence is found, much of the water is excluded as a highly redundant number of contacts evolve between the enzyme and the bases and phosphodiester backbone of the DNA. In the case of EcoRI, 50 water molecules are excluded at the cognate site (6). Generally...
Since the transformed surface has been shown to be concave, the convergence of Newton’s method is ensured. The actual formulation of Newton’s method relies on the implicit function theorem since the relation between the value and the parameter can only be found implicitly as a hypergeometric ...

Describe how to find the mass of an atom. Mass of the Atom: Mass of the atom is the addition of the neutron and proton that are found inside the nucleus of the atom. The SI unit of the mass of the atoms is a kilogram, but it is usually represented in a.m.u(atomic mass unit)...
Fortunately, the molar mass allows one to relate several quantities that describe the amount of a substance, whether it is an element or compound. The molar mass, or sometimes called atomic mass or molecular weight, is defined to be the mass of a particular element or compound over 1 mole ...
