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.
Calculate the molarity of the following solution:
(a) 29.0 g of ethanol (C2H5OH) in 545 mL of
solution
M (molarity) = moles of solute/ liters of solution
Molarity = moles of solute / L of solution
use the equation:
MaVa = MbVb
Where M is Molarity and V is volume
Molarity= (number of moles of solute)/(volume of solution in dm3)
it is M=g/L where m=molarity, g= grams, and l= liters.
moles of solute/ volume of solution
Number of Moles = concentration * volume (in litres)

Titration is used to calculate the molarity of an acid or base (standardising), using a base or an acid respectively with a known molarity (primary standard).
Number of Moles = concentration * volume (in litres)
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!!!
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
I believe you mean molarity. Molarity is a unit of concentration. So if the number is twice as big...

In moles of a substance dissolved in 1 L of water.
Knowing the solubility of an unknown substance in water can help you calculate its molarity. It is however important to get its weight first.
