Molarity (M) = mole of solute (mol)/volume of solution that it is dissolved into (L)

Make sure that the volume is converted to L if it isn't already, otherwise you will get wrong answers.

use the equation:

MaVa = MbVb

Where M is Molarity and V is volume

it is M=g/L where m=molarity, g= grams, and l= liters.

### How do calculate molarity example being calculate molarity of 6.5g of hcl solution per liter solution?

All you have to do is convert the 6.5 g HCl solution into moles, and then plug that value into the molarity formula. If you need help, here are the formulas: # mol = (mass of substance)/(molar mass) - the molar mass is just the molecular mass of the substance expressed in grams :) Molarity (M) = (# mol solute)/(# L solution) - the solute, in this case, is the HCl, and the solution is just one, based on your question Happy Calculating!!!
