In chemistry, the mole fraction or molar fraction (xi or χi) is defined as unit of the amount of a constituent (expressed in moles), ni, divided by the total amount of all constituents in a mixture (also expressed in moles), ntot. This expression is given below: The sum of all the mole fractions is equal to 1: The same concept expressed with a denominator of 100 is the mole percent, molar percentage or molar proportion (mol%). The mole fraction is also called the amount fraction.
In chemistry, the mass fraction of a substance within a mixture is the ratio (alternatively denoted ) of the mass of that substance to the total mass of the mixture. Expressed as a formula, the mass fraction is: Because the individual masses of the ingredients of a mixture sum to , their mass fractions sum to unity: Mass fraction can also be expressed, with a denominator of 100, as percentage by mass (in commercial contexts often called percentage by weight, abbreviated wt%; see mass versus weight).
Conservatism is a cultural, social, and political philosophy that seeks to promote and to preserve traditional institutions, practices, and values. The central tenets of conservatism may vary in relation to the culture and civilization in which it appears. In Western culture, depending on the particular nation, conservatives seek to promote a range of social institutions such as the nuclear family, organized religion, the military, property rights, and monarchy.
Conservative liberalism, also referred to as right-liberalism, is a variant of liberalism, combining liberal values and policies with conservative stances, or simply representing the right-wing of the liberal movement. In the case of modern conservative liberalism, scholars sometimes see it as a more positive and less radical variant of classical liberalism; it is also referred to as an individual tradition that distinguishes it from classical liberalism and social liberalism.
The Conservative Revolution (Konservative Revolution), also known as the German neoconservative movement, or new nationalism, was a German national-conservative movement prominent during the Weimar Republic, in the years 1918–1933 (between World War I and the Nazi seizure of power). Conservative Revolutionaries were involved in a cultural counter-revolution and showed a wide range of diverging positions concerning the nature of the institutions Germany had to instate, labelled by historian Roger Woods the "conservative dilemma".
