valkas [14]

Answer: A 13.88 mL of the concentrated acid would be required to make 250. mL of a 1.00 M H_{2}SO_{4} solution.

Explanation:

Given: M_{1} = 18.0 M,     V_{1} = ?

M_{2} = 1.00 M,         V_{2} = 250 mL

Formula used to calculate the volume of concentrated acid is as follows.

M_{1}V_{1} = M_{2}V_{2}

Substitute the values into above formula as follows.

M_{1}V_{1} = M_{2}V_{2}\\18.0 M \times V_{1} = 1.00 M \times 250 mL\\V_{1} = \frac{1.00 M \times 250 mL}{18.0 M}\\= 13.88 mL

Thus, we can conclude that 13.88 mL of the concentrated acid would be required to make 250. mL of a 1.00 M H_{2}SO_{4} solution.
