Describe how to prepare 1.00 L of 0.646 M HCl solution, starting with 2.00 M HCl solution.

Question

photon336 · Answer

It's been a while but I think it may be this: 

$$M_{1}V_{1} = M_{2}V_{2}$$ 


$$\frac{ M_{1}V_{1} }{ M_{2} } = V_{2}$$

$$\frac{ 1.0L*0.646M }{ 2.00M } = 0.323 L $$

we would need 323 mL of a 2.0M solution 


@Rushwr your help is needed
