molecular weight - (chemistry) the sum of the relative atomic masses of the constituent atoms of a molecule relative molecular mass mass - the property of a body that causes it to have weight in a gravitational field chemical science, chemistry - the science of matter; the branch of the nat...
1.(Chemistry) (of a physical quantity) per unit amount of substance:molar volume. 2.(Chemistry) (not recommended in technical usage) (of a solution) containing one mole of solute per litre of solution [C19: from Latinmōlēsa mass] ...
Mole formula is: Mole = Mass / Molar mass According to the mole formula, the moles can be obtained by dividing the mass by the molar mass. How do you calculate molar mass? Molar mass is calculated as a total of the atomic masses of all atoms that are present in a given compound. ...
Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul
In chemistry, the gas constant goes by many names, including the ideal gas constant and universal gas constant. It is the molar equivalent to the Boltzmann constant. The SI value of the gas constant is exactly 8.31446261815324 J⋅K−1⋅mol−1. Usually, the decimal is rounded to 8.314...
For example, H2O molecules have a similar molar mass to CH4molecules. Water boils at 100 °C and methane boils at -161.5 °C. The large difference in boiling points arises from theelectronegativitiesof hydrogen and oxygen producing a dipole in the water molecule. Water is a polar molecule;...
Mole, standard unit (6.02214076 x 10^23) in chemistry for measuring large quantities of very small entities such as atoms, molecules, or other specified particles. The number of units in a mole also bears the name Avogadro’s number, or Avogadro’s const
In chemistry, a base is a chemical species that donateselectrons, acceptsprotons, or releases hydroxide (OH-) ions in aqueous solution. Bases display certain characteristic properties that can be used to help identify them. They tend to be slippery to the touch (e.g., soap), can taste bitt...
