(n a ). from the above discussion, we can say that the number of atoms present in 1 mole of hydrogen is equal to 6.022×10 23 . mole definition in chemistry, the mole is a fundamental (si) unit used to measure the amount of substance. this quantity is sometimes referred to as the...
Molar Volume Formula The Molar volume is directly proportional to molar mass and inversely proportional to density. The formula of the molar volume is expressed as Where Vmis the volume of the substance. The standard temperature used is 273 Kelvin or 0oC, ...
In chemistry—where the amount of a substance is usually measured in moles, not grams—further modifying the definition and formula of heat capacity to include moles makes things a lot easier. Molar heat capacity is defined as the amount of heat required to raise 1 mole of a substance by 1...
The volume fraction of species i can be expressed in terms of the volume ratio as: (9.18)σi=nik1+∑j≠knjk In the following formulations, the various phases (solid and fluid) in porous media are denoted by j; w, o, and g denote the water, oil, and gas phases, respectively; s ...
In subject area: Chemistry Molar Excess Gibbs Free Energy refers to the additional Gibbs free energy associated with the mixing of substances in a system, excluding the contribution from the ideal entropy of mixing and volume effects. It is a measure of the non-ideal behavior of a mixture. ...

In Chemistry, Colligative properties are those properties of solutions that depend on the ratio of the number of solute particles to the number of solvent Molecules in a solution and not on the nature of the chemical species present. Colligative properties include following four main properties – ...
Now assuming that the mass gain is entirely caused by oxygen (molar mass of 16 g/mol), the molar mass of the starting material can be calculated with a simple ratio according to the following equation: (3.2)xgmol100%=16gmol65%=24.6g/mol which happens to be close to the tabulated ...
