This calculation means that you need one mole of salt. Now, you need to use the molar mass of salt in order to calculate how much you need to weigh out. 1mol(58.44g1mol)=58.44g This calculation means that if you wanted to make a 1 liter solution of 1M NaCl, you would need to w...
To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...
Molar Mass of HCl: 36.46 g/mol ElementSymbolAtomsMass % Hydrogen H 1 2.8% Chlorine Cl 1 97.2% While molarity is usually a convenient way to talk about concentration, sometimes there aren't actually that many moles in the solution. What does that mean? Well, say you have a 0.001 M so...
Re: How do you calculate the molar mass? « Reply #3 on: February 18, 2008, 01:18:53 PM » you have 8 parts of H20, the molar mass of H20 is 18, simply multiply 8 with 18 and add to the rest of the mass « Last Edit: February 18, 2008, 01:30:27 PM by Tomce »...
Molecularmass=2×Vapourdensity(VD)Empirical formulas can be determined from the percentage composition of a compound. However, to determine its molecular formula, it is necessary to know the molar mass of the compound.Steps to Calculate Molecular formula of all Elements...
Learning how to calculate molarity isn't difficult; the key is to remember the units of molarity (M): moles per liter. Find the molarity by calculating the number of moles of the solute dissolved in liters of a solution. Molarity is a unit of concentration, measuring the number of moles...

Molarityis one of the most common units of concentration. It is used when the temperature of an experiment won't change. It's one of the easiest units to calculate. You get the mass of solute for the solution, mix the solute with a known volume of solvent, and divide mass by volume ...
To calculate the molar mass,the atomic mass of each substance is multiplied with the subscript of that element in the chemical formula. Then the masses of all the elements are added. \[{{\rm{H}}_2}{\rm{O}}\] represents water. ...
