# What is the new concentration of a 50*mL volume of 3.3*mol*L^-1 HCl(aq) that is diluted to a 350*mL volume with fresh water solvent?

You usually add acid to water.........

#### Explanation:

But since this was a fairly dilute solution, you would probably get away with this order of addition:

$\text{Concentration}$ $=$ $\text{Moles"/"Volume}$

$\frac{3.3 \cdot m o l \cdot {L}^{-} 1 \times 0.050 \cdot L}{350 \times {10}^{-} 3 \cdot L} = 0.47 \cdot m o l \cdot {L}^{-} 1$ with respect to $H C l$.

With more concentrated acid solutions the order of addition is ALWAYS ACID TO WATER..................
