Understanding Molarity Calculations
Molarity ($M$) measures the concentration of a chemical solute dissolved inside a fluid solvent solution. The relationship is governed by three variables:
1. The Molarity Formula:
Molarity (M) = Moles of Solute / Liters of Solution ($V_L$)
2. Moles to Grams Mass Conversion:
To find the mass in grams ($m$) from the count of moles ($n$), multiply by the substance Molar Mass ($MW$ in g/mol):
Moles (n) = Mass (g) / Molar Mass (g/mol)
Mass (g) = Molarity (M) * Volume (L) * Molar Mass (g/mol)
Mass (g) = Molarity (M) * Volume (L) * Molar Mass (g/mol)
3. Volume Equations:
Volume (L) = Mass (g) / ( Molarity (M) * Molar Mass (g/mol) )
