Some basic concept of chemistry

Temperature in oF=(95)oC+32Temperature in oF=(95)oC+32

Relative atomic mass =Mass of an atom of the element112x Mass of an atom of carban(C-12)Relative atomic mass =Mass of an atom of the element112x Mass of an atom of carban(C-12)

Number of gram molecules =W(g) Gram molecular massNumber of gram molecules =W(g) Gram molecular mass

Number of gram atoms=W(g) Gram Atomic Mass(GAM)Number of gram atoms=W(g) Gram Atomic Mass(GAM)

Avogadro's number NA=6.022X1023Avogadro's number NA=6.022X1023

Mass of one atom of element =GAMNAMass of one atom of element =GAMNA

Mass of one molecule of substance =GMMNA ( where GMM is Gram molar mass)Mass of one molecule of substance =GMMNA ( where GMM is Gram molar mass)

Number of molecule in W(g) of substance =W(g)xNAGMMNumber of molecule in W(g) of substance =W(g)xNAGMM

Mass % of an element in a compound =Mass of that element in 1 mole of compoundMoler mass of the compound x 10Mass % of an element in a compound =Mass of that element in 1 mole of compoundMoler mass of the compound x 10

Mass percent =Mass of soluteMass of solution x 100Mass percent =Mass of soluteMass of solution x 100

Molarity(m) =Number of moles of soluteMass of solvent in kgMolarity(m) =Number of moles of soluteMass of solvent in kg

Molecular mass =2 x vapour density
