Answer to Question #150787 in General Chemistry for jose

Question

How many Liters of 2.5 M Hydrochloric acid should we use if you have 0.5mol of HCl available.

Answer 1

Concentration = $\frac{No. of moles of solute }{Volume of solvent}$

Here C is 2.5 M

No.of moles of HCl required is 0.5 mol

Therefore, Volume of solution = $\frac{No. of moles of solute}{Concentration}$

= 0.5/2.5 L = 0.2 L
