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...
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 »...
To understand how the mole is related to mass, volume, and the number of molecules of a substance, we can break it down into three parts:(i) Mole and Mass 1. Definition of a Mole: A mole is a unit that measures
The molar solubility is the number of moles that can be dissolved per liter of a solution until the solution becomes saturated. A saturated solution is a solution in which the maximum amount of solute has been dissolved. An unsaturated solution is a solu
