Calculate Molar Mass

In order to grasp the concept of molar mass calculations it is important to understand the molar unit.This app you can use for computing the average molecular weight (MW) of chemical compound by entering the chemical formulas (for example NaCl ). To calculate molar mass of a chemical compound enter its formula and click 'Calculate'. This app will let you calculate mass of chemical compound needed for number of moles.You can choose by one of the next two option-lists, which contains a series of common organic compounds (including their chemical formula). The molar mass calculator will recognize the entered formula's, which are included in the list of organic compounds.

The mass and molarity of chemical compounds can be calculated based on the molar mass of the compound. The mass (in grams) of a compound is equal to its molarity (in moles) multiply its molar mass: grams = mole × molar mass.Select Chemical Compound to get Molar Mass

Molarity refers to the molar concentration of a solution, that is, the number of moles of solute dissolved in 1 liter of solution, as mol/L, abbreviated as M.

Molarity Calculator Equation:
Molarity = Mass / (Volume × Molar Mass);
Mole = Concentration (g/L) × Volume (L) / MW (g/mol);

Molarity Calculation Example:
(1) Calculate moles of a 15ml NaCl solution with concentration 0.2g/L
The molar mass of NaCl is 58.44276 g/mol (Click here for molar mass calculator). So:
mole = 0.2 * (15 / 1000) / 58.44276 = 0.000051332278 (mol)

(2) What's the mass of NaCl required to make a 0.2mol/L solution in 15ml of water?
The molar mass of NaCl is 58.44276 g/mol.
So:
Mass = 0.2 * (15 / 1000) * 58.44276 = 0.175328 (gram)
