I assumed there wouldn't be enough solute to drastically affect density and so I changed 1 L to 1000g, so I now have mol/1000g. Then I multiply by the molar mass of the solute (NaOH - 39.998) so I'm now g NaOH/1000g solution. Then I multiply the whole thing by 1000 to get ppt, right? order glasses online with a prescriptionWebMole Concept In chemical applications, the moral ideal is a simple and convenient way to quantify the amount of a substance.
