K + MgBr2 = KBr + Mgsingle replacement
K + Cl2 = KClsynthesis
K + B2O3 = K2O + Bsingle replacement
Formula in Hill system is K

Computing molar massive (molar weight)

To calculate molar mass of a chemical compound enter its formula and click "Compute". In chemical formula you may use:Any chemical element. Capitalize the very first letter in chemical symbol and also use lower instance for the continuing to be letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al.Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmgparantesis () or brackets <>.Common compound names.Examples the molar massive computations: NaCl, Ca(OH)2, K4,CuSO4*5H2O,water,nitric acid,potassium permanganate,ethanol,fructose.

You are watching: What is the molar mass of potassium

Molar massive calculator likewise displays typical compound name, Hill formula, elemental composition, mass percent composition, atom percent compositions and allows to transform from load to variety of moles and vice versa.

Computing molecular weight (molecular mass)

To calculation molecular weight of a chemistry compound get in it"s formula, clues its isotope massive number ~ each element in square brackets.Examples the molecular load computations: C<14>O<16>2, S<34>O<16>2.

Definitions of molecular mass, molecular weight, molar mass and molar weight

Molecular mass (molecular weight) is the massive of one molecule that a substance and also is express in the linked atomic mass devices (u). (1 u is same to 1/12 the mass of one atom that carbon-12) Molar mass (molar weight) is the fixed of one mole the a substance and also is expressed in g/mol.Weights of atoms and isotopes are from NIST article.Related: molecular weights the amino acidsmolecular weights calculated today please let us know just how we can improve this web app.
