![]() Please let us know how we can improve this web app. Related: Molecular weights of amino acids ![]() Weights of atoms and isotopes are from NIST article. Sodium Hydroxide Molecular Weight Calculation To calculate molecular weight of any compound. Molar mass ( molar weight) is the mass of one mole of a substance and is expressed in g/mol. The molecular weight of Sodium hydroxide (NaOH) is 39.996769.(1 u is equal to 1/12 the mass of one atom of carbon-12) Molecular mass ( molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u).To calculate molecular weight of a chemical compound enter it's formula, specify its isotope mass number after each element in square brackets.Įxamples of molecular weight computations:ĭefinitions of molecular mass, molecular weight, molar mass and molar weight Molar mass calculator also displays common compound name, Hill formula, elemental composition, mass percent composition, atomic percent compositions and allows to convert from weight to number of moles and vice versa.Ĭomputing molecular weight (molecular mass) Consider the example given below 0.25 mol/L solution of sodium hydroxide means that 0.25 moles of sodium hydroxide have been dissolved in the 1 litre (or 1 cubic decimetre) of the solution. Functional groups: D, Ph, Me, Et, Bu, AcAc, For, Ts, Tos, Bz, TMS, tBu, Bzl, Bn, Dmg The standard unit of Molarity is moles/L, or Molar or M.Match the words in the left column to the. ![]() Complete the following sentences regarding the concentration of the prepared solution. It is a white solid ionic compound consisting of. Transcribed image text: You need to prepare a 2.40 Msolution of sodium hydroxide (molar mass of sodium hydroxide 40.00 g/mol), but you only have a 10 mL graduated cylinder and a 25 mL beaker. Capitalize the first letter in chemical symbol and use lower case for the remaining letters: Ca, Fe, Mg, Mn, S, O, H, C, N, Na, K, Cl, Al. Sodium hydroxide, also known as lye and caustic soda, is an inorganic compound with the formula NaOH. Computing molar mass (molar weight)To calculate molar mass of a chemical compound enter its formula and click 'Compute'.
