Molar concentration is the number of moles of solute in one litre of solution. "M" is used to denote molar concentration with units of moles/litre.
Formula: Molarity = moles of solute (mol)/ volume of solution (L)
Examples:
If there is 1.5 moles of NaCl in 1.0L of soltuion, what is the molar concentration?
M= 1.5mol NaCl/1.0L
= 1.5M NaCl or 1.5mol/L NaCl
