From the periodic table the molar masses of the compounds will be extracted. To convert grams to moles, the molecular weight of the solute is needed. The number of moles represents the fraction: mass of the compound / molecular weight of the compound. Here are the conversions: 1 mol/L (M) equals to Unit of measurement : SI: The concentration may also be expressed in different fractions of the molar concentration such as mmol/L (mM), μmol/L (μM), nmol/L (nM), pmol/L (pM). It is defined as the number of moles in a solution. This is the same with molar concentration and represents the concentration of a solute in a solution. Concentration – expressed in either molar, milimolar, micromolar, nanomolar, picomolar or femtomolar.Transcribed image text: Sodium carbonate (Na2CO3) has a molar mass of 105.99 g/mol. Mass – expressed in either grams, milligrams, micrograms Answer 4: Molar Mass of NaCO 105.99 Then 34.1 g sample is 34.1/105.99 mole 0.321 Mole Hence 0.321 Mole of Sodium carbonate are contained in 34.1 gm sample.Volume – expressed in either liters, milliliters or microliters.To compute any of the elements in the molarity equation you need to input the other three and choose the desired measurement unit. There are four components in the equation therefore there are four fields in the molarity calculator.
Please let us know how we can improve this web app.This is a great chemistry tool for those who need to determine a solution’s molar concentration from the mass, volume and molecular weight. Related: Molecular weights of amino acids
Weights of atoms and isotopes are from NIST article.
