Say you need to make a solution of 1M NaCl for a reaction you are running. How would you know how much salt to weigh out and then add to a given volume of water? To do this, you need to find a way to relate the mass of a compound (salt) to the number of moles of that comp...
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...
The molar mass of any solid, liquid, or gaseous substance is the number of grams of the substance in its molecular (molar) form that contains 6.0221367 X e^23 atoms of the substance (Avogadro's Number). This is because the mass of a substance is dependen
Re: How do you calculate the molar mass? « Reply #8 on: February 18, 2008, 09:49:07 PM » Just for the record, when you have H20 trapped like that, it's called a hydrate. Just a little snippet of info that might be useful to you sometime Logged Print...
How to Calculate the Stoichiometric Ratio. Stoichiometry is a type of math associated with chemistry. In stoichiometry, you perform calculations pertaining to moles (the basic unit of weight in chemistry), masses and percentages. A stoichiometric ratio s
Moles to Atoms | Formula, Calculation & Avogadro's Number from Chapter 2 / Lesson 4 212K What is the moles to atoms formula? How does one convert atoms to moles? Learn how to calculate the number of atoms in a sample from the relationship between moles and Avogadro's nu...
The mole to mass conversion is useful having identified a molar amount from a balanced equation and now needing to find the mass of reactant used. The molar amount has to be multiplied by the molar mass of the chemical species to obtain mass....
Using this law, we can calculate the rate of diffusion or effusion of molar masses of unknown gases using the molar mass of the given gas. The main application of this law is to separate the gases having different densities.A...
How to Calculate Alkalinity After Titration Updated April 24, 2017 By Philip J. Carlson Titration is used to determine the concentration of an unknown substance via the molar relationship expressed through the chemical reaction equation. Using these relationships, the pH value can be determined by c...
Set up the following equation relating grams to moles: x moles H2O = (1 mole H2O/18 grams H2O) x (600 grams H2O) Step 3 Solve the equation in Step 2 to find that there are 3.33 moles of H2O in 600 grams of H2O. References Stoichiometry How to calculate the molar masses of chemical...
