Question:

27. What volume of 12.389 M concentrated solution of HCl is required to make 1.00 litre of 0.010 M HCl?

Solution:

The amount of a substance (n) of HCl in the resulted solution is:

$$n = C * V = 0.01 * 1 = 0.01 \text{ mole}$$

The required volume ($V_{HCl}$) of 12.389 M concentrated solution of HCl will be:

$$V_{HCl} = n / C = 0.01 / 12.389 = 8.07 * 10^{-4} \text{ L} \ (0.807 \text{ ml})$$

Answer: 0.807 ml.
